Preface

This report updates population and housing trends within Community

High School District 99 and assesses the implications of these trends for future

enrollments at North High School and South High School. As in my prior

studies, the objective of the current report is fourfold. First, I shall update

residential development patterns and demographic dynamics underlying

enrollment change in the District. Next, I shall assess annual enrollment changes

in the K–8 feeder districts, District 99 as a whole, and the two high schools

during the past thirty years and analyze the sources of these enrollment changes.

I shall then discuss the factors that will shape future enrollments at the high

schools. Finally, I shall project enrollment for North and South High Schools

through school year 2031–32, by grade and by year.

All enrollment projections will be in the form of three separate series

based on different assumptions about future new residential development,

housing turnover, and family migration to District 99. The three series will

provide grade-by-grade, year-by-year forecasts of (A) the absolute minimum

number of students that may be anticipated, (B) the most likely number of

students to be expected, and (C) the absolute maximum number of students that

can be foreseen.

In conducting the analysis that follows, I benefited from data provided by

administrators of District 99 and local village officials. I would like especially to

acknowledge Mr. Pete Theis, Assistant Superintendent for Human Resources,

who coordinated assembly of much of the information upon which this study is

based. For his fine assistance, and that of all the others who participated in this

endeavor, I am most appreciative.

Overview of Community High School District 99

Community High School District 99 is located in Chicago’s western

suburbs, approximately nineteen miles from the Loop. The District, which covers

a thirty-two square-mile area, serves students in grades 9 through 12 on two

campuses: North and South. This past Fall, records showed 2,231 students

attending North High School and 2,695 students attending South High School,

making total District enrollment 4,926. These students come from eight villages

and unincorporated portions of DuPage County. The primary villages include

Downers Grove, Woodridge, Darien, and Westmont with very small percentages

from Bolingbrook, Oak Brook, Lisle, Naperville, and unincorporated DuPage

County.

Public elementary sending districts include Downers Grove #58, Maercker

#60, Darien #61, Center-Cass #66, and Woodridge #68. In 2016–17, North High

School received 59 percent of its students from District 58, 19 percent from

District 68, 10 percent from District 60, and 12 percent from other, while South

High School received 35 percent of its students from District 58, 30 percent from

District 68, 17 percent from District 66, 12 percent from District 61, and 6 percent

from other.

Since its founding in 1923, Community High School District 99 has grown

from one small building to two large modern comprehensive high schools, and

3


from five original graduates to approximately 1,200 graduates last year. North

High School opened its doors in 1928. To accommodate rapid growth in

District 99 villages, South High School was completed in 1964.

Since their early days, both schools have undergone major additions and

renovations to accommodate growth and changes in education. In the last fifteen

years, these have included additional contemporary classrooms, modern

technology laboratories, multiple student resource centers, new science

laboratories, an extensive fine arts wing, a new field house and expanded

commons areas, as well as major outdoor improvements. New technology

infrastructure was included in almost all facility expansions and upgrades.

The District's two high schools have exhibited excellent academic and

extra-curricular achievements over the years. In 2016, US News & World Report

ranked North High and South High School each as a “Silver Medal School.”

Housing and Population Trends

Like many of Chicago’s well-established suburbs, the District 99 area

experienced a flurry of new housing construction in the 1960s and 1970s. The

2010–2014 American Community Survey estimates that during these two

decades 8,701 housing units were built in Downers Grove and 6,849 in

Woodridge (see Table 1). The vast majority of these homes were single-family,

detached structures containing three or more bedrooms. Furthermore, these

homes were reasonably priced. Table 2 reveals that as late as 1970 the median

value of owner-occupied units in Downers Grove was $27,200; Woodridge,

$29,200; Darien, $34,600; and Westmont, just $19,900. The substantial amount of

construction of moderately priced housing during the 1960s and 1970s attracted

large numbers of younger couples with preschool and school-age children to the

District.

Table 3 describes the population trends since 1950 for the villages served

by District 99. Between 1960 and 1980 Downers Grove grew from 21,154

residents to 42,572. During this same period, Woodridge expanded from 542 to

22,322, Darien (incorporated in 1969) from a small unrecorded number to 14,536

and Westmont from 5,997 to 16, 718.

As new housing construction in the main District 99 villages slowed in the

1980s, so did their residential growth. This slowdown continued in Downers

5


Grove with its population climbing from 46,858 in 1990 to 48,724 in 2000 before

dropping slightly to 47,833 in 2010 and then rising again to 49,372 in 2014.

Woodridge’s growth has been modest but steady, expanding from 26,256 in 1990

to 30,934 in 2000 and continuing to climb to 32,971 residents in 2010 and 33,227 in

2014. The fastest-growth village over the past 20 years, Bolingbrook, has only a

small portion in the South High School attendance area. Both Darien and

Westmont have been essentially stable in their residential counts since 2000.

More important than total population numbers, are the changes in the

preschool and school-age populations in District 99’s villages. Downers Grove,

for example, despite an overall population increase of nearly 10,000 between

1970 and 1980, experienced absolute declines in its preschool residents (under

age 5) as well as those aged 5 to 9 and 10–14.

With mortgage interest rates falling in the mid-1980s and with growing

numbers of empty nest households, housing turnover accelerated and more

young families began to move into the District, despite appreciating housing

costs. Sustained lower mortgage interest rates, together with a solid rebound in

the Chicago area economy, led to continuing housing turnover to younger

families during the 1990s, particularly in the older sections in the north of the

District. As a result, Downers Grove saw its preschool (under age 5) population

swell from 2,842 in 1980 to 3,656 in 1990 while its population aged 5–9 grew from

3,099 to 3,323. Woodridge experienced similar growth in these age groups.

6


Table 3 also reveals that despite increased housing turnover to younger

families, Downers Grove has a large and growing number of residents over age

65. Woodridge, Darien, and Westmont exhibit a similar growing retirement age

pattern. This would suggest that, barring a prolonged recession, the likelihood is

for increasing housing turnover to younger families in District 99 during the next

15 years. Countering this is a drop between 2000 and year 2014 in Downers

Grove preschool (under age 5) population and an even greater drop in

Woodridge (from 2,361 to 2,060) which will eventually impact District 99 high

schools, though Downers Grove did exhibit a rebound in its under age 5

population between 2010 and 2014. Darien's and Westmont's under age 5

populations are lower in 2014 than in 2000.

Along with increased housing turnover, District 99 has experienced some

new housing construction over the past 15 years. However, the 2007–2011

financial crisis had a major impact on new housing construction in most of

District 99 as did residential build-out. Table 4 displays the annual new housing

construction permits through September 2016 for the villages served by

District 99. The drop in new housing construction since 2007 can be clearly

observed. It should also be noted that these figures include some teardowns of

older housing and their replacement by new construction. Downers Grove, for

example, has been averaging approximately ten teardowns/rebuilds a year

according to local officials.

Enrollment Trends and Student Migration/Transfer

Enrollment trends in local public schools mirrored community

demographic dynamics. Total elementary and high school enrollments

mushroomed in the 1950s and 1960s. Enrollment growth in the elementary feeder

school districts to North and South High Schools slowed considerably in the

1970s and most started to decline. These declines continued until the mid-1980s,

at which point the elementary feeder district enrollments either stabilized or

began to rise again. Total elementary school feeder enrollment (sum of the public

elementary feeder districts) expanded through school year 1994–95, and declined

modestly thereafter through school year 1997–98. A large decline shown between

school year 1997–98 and 1998–99 is primarily an artifact of enrollment data from

Darien #61 and Maercker #60 being reported in 1998–99 and thereafter for only

their students who resided within District 99 boundaries. Prior years include all

enrolled students in these districts. Total elementary feeder district enrollment

continued to decline (details presented shortly) through school year 2005–06.

Since then it has roughly stabilized.

District 99 High School enrollment also rapidly increased throughout the

1950s, 1960s, and early 1970s. Table 5 shows that total high school enrollment,

which climbed to 5,979 in school year 1975–76, dropped by more than 1,000

students during the following eight years to 4,976 students in 1983–84. Total

12


District 99 enrollment followed a mild roller coaster pattern since that school

year, rising to 5,290 students in 1986–87 then falling to 4,757 students in 1989–90

before climbing again to 5,677 students 2006–07. Total high school enrollment

then declined to 5,269 students in 2009–10, rebounded to 5,328 students in

2010–11, then fell to 4,958 students in 2012–13 before roughly stabilizing through

this school year with 4,926 students registered.

Table 5 reveals that North High School and South High School also

experienced modest roller coaster enrollment patterns during the past 40 years

with a somewhat more significant dip at North High School before it rebounded

in the 1990s. Between September 2002 and September 2004 there was a

substantial increase in enrollment in District 99 (5,316 to 5,605) with South

jumping from 3,152 in 2002–03 to 3,334 in 2003–04, before slipping back to 3,189

in 2007–08. After staying near that number through 2010–11, South's enrollment

dropped to 2,685 students in Fall 2015 and stabilized again. North climbed from

2,164 students in 2002–03 to 2,363 in 2006–07 then fell back to 2,169 in 2008–09

before roughly stabilizing since then with Fall 2016 enrollment at 2,231.

Let me now turn to the specifics of enrollment changes in District 99's

elementary feeder districts and District 99's high schools by elaborating their

determinants.

13


Determinants of Enrollment Change

School districts are open demographic systems whose growth, stability, or

decline is affected by three basic factors. The first is the difference between the

size of the kindergarten (or for the high school district, ninth grade) class that

enters each September and the size of the previous June’s graduating class (either

eighth or twelfth grade). The second is the net migration/transfer of school-age

children in each district as they progress through the grades over the years. The

third is annual change in special education and early childhood classes, should

these be tabulated separately.

Tables 6, 7, and 8 show how annual total enrollment change in the

combined public elementary districts that feed students to District 99 may be

decomposed into these three component parts since school year 1987–88. Table 6

provides the grade-by-grade and year-by-year combined enrollment for the

public elementary feeder districts, with elementary totals after 1997–98 including

only students from Darien and Maercker residing in District 99.

Table 7 decomposes the annual total enrollment changes into the three

component parts. Thus, between September 2015 (school year 2015–16) and

September 2016 (school year 2016–17) combined public feeder school enrollment

declined by 44 students (11,306 to 11,262; see Table 6). The 1,201 eighth graders

who left the public elementary districts in June 2016 (see Table 6) were replaced

this past September by 1,087 kindergarten students, for a net class size difference

14


of –114. At the same time, 79 more students either migrated into the elementary

school districts or transferred from private schools than migrated out of the

districts or transferred to private schools. Also, between September 2015 and

September 2016, special education students declined by two and early childhood

declined by seven students. Summing these figures (–114, +79,–2,–7) gives the

exact number that total enrollment changed in the feeder districts between

September 2015 and September 2016 which is –44.

Note that despite annual net student migration/transfer gains for the

elementary districts during each of the past eighteen years, these gains were

sometimes overwhelmed by much smaller entering kindergarten class sizes

compared with the previous June’s graduating eighth grade class sizes. This

resulted in a total elementary school enrollment drop for those years.

Table 8 shows the grade-by-grade, year-by-year net student migration/

transfer figures for the combined elementary sending districts. For example, the

“104” at the bottom of the K–1 column means that as the kindergarten class of

school year 2015–16 progressed to the first grade in school year 2016–17, it

gained 104 students via net student migration or transfer (see Table 6 where this

class grew from 1,112 to 1,216 as it progressed upward one grade level).

Conversely, as the first grade class of 2015–16 (1,188 students) progressed to the

second grade in 2016–17 (1,186 students), it declined by two students. Summing

across the bottom row of Table 8 gives the total K–8 net student migration/

15


transfer between September 2015 and September 2016; which is +79, the figure

shown in Table 7.

Appendix A provides enrollment histories by year and by grade for the

past thirty years for each public elementary feeder district. It also presents the

decomposition of annual sources of enrollment change for each district and their

annual migration/transfer figures. These tables should be interpreted in the

same manner as Tables 6, 7, and 8 for the aggregated public elementary feeder

districts.

Suffice it to note that the Puffer-Hefty District 69 was dissolved as a legal

entity on July 1, 2004, and all of their students were assigned to Downers Grove

District 58. Thus, beginning with the 2004–05 school year, the K–6 students

remained in the Henry Puffer Building, but their enrollment numbers are

included with the enrollment numbers for each of the grades in District 58. The

Puffer-Hefty seventh and eighth grade students were all moved to Herrick

Middle Schools in District 58. The seventh and eighth grade enrollment numbers

for District 58 therefore include the seventh and eighth grade students that

previously were housed in the Henry Puffer building. In the net, then, with

regard to longitudinal analysis, while two districts are now legally one, the

student base that feeds District 99 (and specifically North High School) has not

changed.

16


Tables 9, 10, and 11 show how annual total enrollment change in

District 99 since September 1986 may be decomposed into its two component

parts, entering ninth grade versus the prior year’s graduating twelfth grade class

and student net migration/transfer (including any school dropouts). Since

special education students are included in the grade-by-grade totals, this

component is not separated out.

Table 9 presents the annual District 99 combined high school enrollments

by grade for the past thirty years. Annual changes in District 99 enrollment are

then decomposed in Table 10. For example, between September 2015 (school year

2015–16) and September 2016 (school year 2016–17), District 99 enrollment grew

by 60 students (from 4,866 to 4,926). The 1,200 twelfth graders who left the

District in June 2016 were replaced this past September by 1,279 ninth graders,

for a net class size difference of +79. However, between September 2015 and

September 2016, nineteen more high school students either migrated out of

District 99, dropped out, or transferred to private/parochial schools than

transferred from private/parochial schools or migrated into District 99 (see

Table 10).

Table 11 describes how the net student migration/transfer (including

dropouts) gains and losses were computed from the enrollment data. Again, the

bottom left cell of “–51” means that as the ninth grade class of September 2015

progressed to the tenth grade in September 2016, it lost 51 students (see Table 9

17


where ninth grade class size in school year 2015–16 was 1,235 and the tenth

grade class size in school year 2016–17 is 1,184 students). During the same

period, the tenth-to-eleventh grade progression lost 31 students while the

eleventh to twelfth grade progression gained 63 students. Summing across the

bottom row in Table 11, one obtains –19; which is the net student migration/

transfer loss shown in Table 10.

Tables 12 through 17 provide grade-by-grade enrollment histories and the

decomposition of annual enrollment change since school year 1986–87 at North

High School and South High School, along with the annual grade-by-grade

migration/transfer analysis for each high school. The decomposition and

migration/transfer tables should be interpreted the same as Tables 10 and 11 for

the combined high schools.

Appendix B presents annual changes in the racial/ethnic composition of

District 99 students overall and for North and South High Schools from 2000 to

2016. Currently, non-Hispanic Whites make up 73 percent of North's student

today (a modest drop from 84 percent in 2000). At South High School, this figure

is 60 percent, down from 75 percent in 2000. Appendix C provides year 2000 and

year 2010 Census totals by race and ethnicity for the villages served by

Community High School District 99.

The Enrollment Future of Community High School District 99

The critical question, as before, now becomes what will happen to

enrollment at North High School and South High School over the next fifteen

years? My analysis of the demographics of District 99 villages and their

population projections, enrollment change in the public elementary feeder

districts, and likely future housing development, housing turnover, and family

in-migration lead me to forecast that enrollment at both high schools will remain

fairly stable through school year 2031–32 close to their current counts. Before

elaborating on these projections, let’s examine the factors underlying them.

Table 18 provides information on annual births to residents of the villages

served by District 99 from 1989 to 2009 (the latest year available) and estimates

derived from DuPage County births thereafter. Annual births trended

downward in Downers Grove and Woodridge in the ten years between 2004 and

2014, while being more stable in Darien and Westmont. This would indicate that

overall future kindergarten enrollments will not likely grow much in the years

ahead. Contributing to small possible increments in future kindergarten

enrollment and preventing significant future declines in elementary and high

school students is the large number of homeowners over age 65 in the area,

suggesting that housing turnover to younger families with preschool and school-

32


age children should remain significant during the next fifteen years, particularly

given the excellent reputation of District 99 area schools.

Since any changes in resident births after 2016 will not affect high school

enrollment projections prior to school year 2031–32, the most critical factor

determining future enrollment in the high schools is net student in-migration

resulting from new housing in the District and from turnover of existing housing

units. Considering that District 99 is approaching build-out, it is unlikely that

major new housing development will occur, though Downers Grove does

possess multi-family unit construction potential and Woodridge possesses

single-family housing development potential. Local planners forecast as many as

490 multi-family units (mostly two-bedroom apartments) in Downers Grove over

the next five years and 260 single-family units during the same period in

Woodridge. There could be another 250 single-family housing units constructed

in Woodridge between 2021 and 20125. Teardowns and replacements will also

likely continue as will scattered single-lot new housing development throughout

the District.

The main factor, however, impacting future enrollment at the high schools

will be turnover of existing housing and resulting in-migration of families with

preschool and school-age children. This turnover is expected to have a positive

impact on overall population growth in the villages in the years ahead.

33


Such expectations are consistent with forecasts of District 99 village

population and household growth by the former Northeastern Illinois Planning

Commission (NIPC); now the Chicago Metropolitan Agency for Planning). The

NIPC projections (shown in Table 19) suggest that between 2000 and 2040, all

District 99 communities should expand in population size, though these forecasts

seem on the high side to me.

Because future student migration patterns could vary substantially,

predicated on economic conditions and the degree of new housing development

and housing turnover, three sets of enrollment projections, by grade and by year

through school year 2031–32, will be provided for each high school. These

projections will be presented in the form of separate series, based on the

following assumptions:

Series A Enrollment projection assuming new housing development, turnover of existing housing units, and resulting family in-migration are less than anticipated through 2031–32;

Series B Enrollment projection assuming new housing development, turnover of existing housing units, and resulting family in-migration occur as anticipated through 2031–32;

Series C Enrollment projection assuming new housing development, turnover of existing housing units, and resulting family in-migration are greater than anticipated through 2031–32.

The basic methodology used to make the three series of enrollment

projections is a modified cohort survival procedure. Average survival

progressions were computed for each grade transition at each elementary feeder

34


district and District 99 high school for the past four years. These grade-by-grade

average progressions were then adjusted for particular year inconsistencies, then

applied to compute baseline enrollment projections (via conventional cohort

survival techniques) for each elementary district. The sizes of future entering

kindergarten classes were estimated using recent trends in kindergarten

enrollment, birth registration data for the communities in District 99, and

different assumptions about likely new housing development and housing

turnover and resulting family in-migration.

The next step was to adjust projected enrollment each year in grades K

through 8 for anticipated new housing development and housing turnover under

the three sets of assumptions.

Series A projections were made assuming an approximately 15 percent

decline in student in-migration rates (compared to Series B) resulting from less

new development and housing turnover than is currently anticipated. Series C

projections assume that new housing development and housing turnover to

younger families will be 15 percent higher than Series B. It has been my

experience in projecting high school enrollment that actual enrollment outcomes

in the longer term have always fallen within the Series A and Series C

parameters, and typically very close to Series B. Thus, the three series will

provide, by year and by grade through school year 2031–32, (A) the absolute

minimum number of students that may be anticipated, (B) the most likely

35


number of students to expect, and (C) the absolute maximum number of

students that can be foreseen.

To project enrollment at each of the high schools it was necessary to

allocate the eighth grade classes from the elementary feeder districts, private/

parochial schools, and other sources to the appropriate high school. Table 20 lists

the principal sending elementary districts and associated middle schools, and the

District 99 high school to which each middle school sends its eighth grade

graduates. Table 21 provides the percentage of students attending North High

School and South High School for selected school years since 1995–96 from each

sending elementary district, along with the percentage of private/parochial and

out of district students at each high school. As may be observed, these figures

have remained relatively stable in the past few years.

To estimate future ninth grade classes, eighth to ninth grade cohort

transition progressions were developed based on source allocations to each high

school in the last four years. In addition to accounting for local public school

sources, the transition progressions take into account freshmen entering each

high school from private/parochial schools as well as from out of district

schools. Tenth through twelfth grade enrollments were projected at North and

South High Schools using the modified cohort survival technique, adjusted for

Series A, Series B, and Series C assumptions.

Tables 23, 26, and 29 provide the annual enrollment projections for North

High School, South High School, and the combined high schools by year and by

grade through school year 2031–32 under Series B assumptions (the most likely).

If future housing development, housing turnover, and family in-migration occur

as anticipated, Table 23 shows that enrollment at North High School will dip

from 2,231 students this year to 2,191 students in 2018–19. Total enrollment at

North will then inch back up to 2,266 students in in 2020–21, then modestly

fluctuate around that number through 2031–31. With these same Series B

assumptions, Table 26 shows that total enrollment at South High School will be

stable next year very close to its present enrollment of 2,695 then rise modestly to

2,736 in 2019–20. Total enrollment at South will then fall back to 2,623 students in

2024–25 before rebounding the following year to 2,673 students and then roughly

stabilizing near this figure through 2031–32. Combined high school enrollment

(Table 29) under the Series B assumptions (presently anticipated future family

migration) will remain stable next year near the 4,926 students registered this

Fall, then dip to 4,917 student in 2018–19. Total District 99 enrollment will then

rise to 4,991 students in 2020–21 before falling back and leveling off during the

following eleven years around 4,925 students. To reiterate, it is my professional

judgment that the Series B projections are the most likely.

However, if national and regional economic conditions and local housing

markets perform poorly, or if mortgage interest rates rise significantly, housing

41


turnover and family in-migration to District 99 will likely slow. Under these

more conservative (Series A) assumptions, Table 22 indicates that enrollment at

North High School will commence modest annual declines to 1,836 students in

2028–29 and stabilize through 2030–31. With Series A assumptions, enrollment at

South High School will also steadily decline to 2,205 students in 2028–29, then

also roughly stabilize (see Table 25). Combined high school enrollment will drop

to 4,028 students in 2029–30 with Series A assumptions and then modestly rise

through 2031–32 (see Table 28). While Series A projections may be viewed as too

conservative by many, they should not be dismissed out of hand, since, as stated,

a prolonged recession or a return to significantly higher mortgage interest rates

could depress future housing turnover and family in-migration to District 99.

Under greater than anticipated younger family in-migration assumptions

(Series C), Table 24 shows that North High School enrollment will steadily rise to

2,603 students in 2024–25 and then stabilize close to that number through school

year 2030–31. Under these same accelerated housing turnover and family in-

migration assumptions, South High School will rise to 3,211 students in 2029–30,

before leveling off near 3,180 students(see Table 27). Combined high school

enrollments, using Series C rapid growth assumptions, will reach 5,903 students

in 2029–30, then fall back modestly the following two years (see Table 30). Series

C, to reiterate, represents the absolute maximum enrollments that can possibly

be foreseen for North and South High Schools.

Figures 1, 2 and 3 present summaries of historical and projected

enrollments under Series A, Series B, and Series C assumptions for North High

School, South High School, and combined District 99 high schools, respectively.

Concluding Remarks

As stated in my prior reports, no demographer has a crystal ball. In this

updated report I have assembled the best information presently available and

applied professional techniques and judgment to generate the enrollment

projections for North High School and South High School. These projections

should be monitored and updated regularly to insure that policy decisions are

based on the most current and reliable figures. At this time, it is my hope that the

projections and other demographic information contained in this report will be

helpful to the Community High School District 99 Board of Education,

administrators, teachers, and concerned citizens as plans are made for future

space and staff needs at your two high schools.
