Basic requirements for using a household survey to produce good
quality migration data

Presentation Outline
• A Bit of History• Guiding Principles to Measuring Migration• Our Data Sources• Questions We Ask
– Citizenship– Year of Entry– Place of Birth– Change in Residence
6
U.N. principles for improving migration statistics
• Three general problems recognized:
– Missing data (for example, data on emigration)
– Incomplete data (for example, data on undocumented migrants)
– Inconsistent data (for example, data on temporary migrants)
• A crosswalk of operational definitions for immigrant stocks and flows
– Foreign-born, foreign background, country of usual residence, long-term
migrant, short-term migrant
• Common definitions of new migrant typologies needed
– Temporary, circular, labor, irregular migrants
• A compilation of emerging practices for measuring temporary and
illegal migrants
7
Some practical principles• Know exactly what you want to ask
– Legal and social context
– International context
• Ask as little as possible– Respondent burden versus overly simplified questions
• Ask about today if you can– Recall bias
– Some questions must be asked
• Be careful about sensitive questions– Migrant legal status
– Religion

Three Data Sources
Census Long Form
American Community
Survey
Current Population
Survey
Single Day, every decade Monthly rolling survey,
adjusted to July 1 population
Monthly labor force survey
All residents of the U.S.A. U.S. household population,
*excluded group quarters in
2005
U.S. civilian, non-
institutionalized population
About 17 million addresses 3 million addresses 100,000 addresses
Mail-out questionnaires and
follow-up interviews (about
70 percent by mail)
Mail-out questionnaires and
CATI/CAPI (about 50 percent
by mail)
Telephone and personal-visit
interviews (CATI/CAPI)

Citizenship Question• Used to estimate total number of foreign born in the
United States
• Foreign born serves as a proxy for “international migrant”
• No ability to distinguish between “short-term migrants” and “long-term migrants” using this question
• Enumerates person (migrant), not event (migration)
• Country of citizenship (where person is not a citizen of the U.S. or holds dual citizenship) is not asked

Year of Entry Question
• Asks year of entry into the United States• Frequently used as a proxy for date of arrival• Problematic for people who have entered
more than once• Differences in interpretation of question• Year of Arrival (first; most recent) vs. Year of
Entry (first; most recent)

Place of Birth Question
• Used to estimate number of foreign born who are born in a particular country or region of the world
• Previous country of usual residence is not asked; place of birth may serve as a proxy
• Boundary changes require reclassification of some responses
24
Parental Nativity Question
• Reflects U.S. legal definition of citizenship, where children of citizens are citizens
• Allows measurement of the demographic impact of foreign born
• Parents born abroad may still be U.S. citizens• We do not know how people with adopted
children from overseas answer this question
30
Residence One Year Ago Question
• Asks country of prior residence if person lived in a different place one year ago
• Can be used to estimate international migration (events) and migrants (persons)
• No information for people under 1 year old• No residence rules on prior country• Used as proxy for previous country of usual
residence

Survey Year
Lived Abroad 1 year ago
Lived in USA 1 year ago
Year of Arrival
Only half of respondents who arrived during the previous year will report having lived abroad “one year ago”.
The survey will capture only half of potential respondents who arrive during the survey year, all of whom lived abroad one year ago.
