1 Data on International Migration and the Foreign-Born Population from the U.S. Census Bureau Elizabeth M. Grieco Chief, Immigration Statistics Staff Population Division, U.S. Census Bureau Finding and Using the Best Immigration Data Resources: A Seminar on Immigration Statistics Migration Policy Institute and Population Reference Bureau October 16, 2008

2 2 Purpose of Presentation Review some basic migration terms: Immigrant, native, and foreign born Flow vs. stock data Census vs. survey data Discuss the available data sources on: Immigration/migrants (events/flows) Foreign born (population) Review several major Census Bureau data sources Decennial Census American Community Survey (ACS) Other sources of survey data 2

3 3 Things to Consider Before Looking for Data… What do you want to know? What data source, type of data would tell you what you want to know? Where can you find the data you want? 3

4 4 Defining Terms: Immigrant, Foreign Born, and Native Immigrant – Anyone admitted to the United States for lawful permanent residence as defined by the Immigration and Nationality Act –Legal permanent residents (LPRs) include new arrivals and adjustments of status Foreign born – Anyone who is not a U.S. citizen at birth –The foreign born include naturalized U.S. citizens, LPRs, temporary migrants, humanitarian migrants, people illegally present in the United States –NOTE: The foreign-born population includes immigrants (LPRs ). Native – Anyone who is a U.S. citizen at birth 4

6 6 Defining Terms: Cautionary Notes U.S. definition of foreign born different from other countries –U.S. excludes those born abroad of at least one American citizen parent (natives) as foreign born –Other countries, e.g., Australia, include everyone born outside as foreign born –Exercise caution if comparing with data from other countries When analyzing microdata,watch who you include as foreign born –Place of birth – the country where a person was born –Citizenship – the persons citizenship status –Place of birth alone will give you all persons born abroad, including citizens born abroad, so need to cross these variables for foreign-born population 6

7 7 Defining Terms: Flow vs. Stock Data Flow data – The collection or summation of events during a certain period, such as a year –Examples: vital statistics (e.g., births, deaths), administrative or work load statistics (e.g., nonimmigrant admissions, naturalizations, refugee arrivals, visas issued) Stock data – The number of persons at a given date –Examples: survey and census data (e.g., population size by age, sex, race, Hispanic origin, or place of birth) 7

8 8 Flow Data: Examples Department of Homeland Security (DHS) – Administrative/Work Load Statistics –Yearbook of Immigration Statistics –LPR arrivals/adjustments, refugee arrivals, asylees, naturalizations, nonimmigrant admissions, enforcement actions –H-1B application statistics –Temporary Protected Status (TPS) application statistics –Student and Exchange Visitor Information System (SEVIS) statistics State Department – Visa Issuance Statistics Office of Travel and Tourism Industries (OTTI) – Foreign Tourist Arrival Statistics Department of Labor (DOL) – Foreign Labor Certification Statistics These are not population counts! However, DHS Office of Immigration Statistics and other researchers use stock and flow data and various methodologies to estimate the size of some of these populations… 8

9 9 Stock Data: Uses and Sources USES: Can help answer: how many? what kind? where? TYPES OF DATA SOURCES: Censuses provide counts of the population –U.S. Census of the Population (e.g., Census 2000 Short Form/100% Data; Census 2010 Data) Surveys are statistical samples used to estimate the size and characteristics of the population –U.S. Census of the Population (e.g., Census 2000 Long Form/Sample Data) –American Community Survey –Current Population Survey –Others 9

10 10 Census Data on the Foreign Born: Examples Federally-funded, nationally-representative surveys are the best sources of stock data on the foreign born Examples of what you can do with the data: Population size Trends through time Characteristics (e.g., country of birth) Distribution and level of geography Note: Much of this data and information are readily available on the Census Bureaus website (e.g., as microdata to download, as tabulated data, maps, etc.) 10

11 11 Foreign-Born Population: 1990, 2000, and 2007 (in millions) Sources: 1990 and 2000 decennial censuses, 2007 American Community Survey Total population Total foreign born Foreign born as percent of total population

12 12 Number of Foreign Born and the Foreign-Born Population as a Percent of the Total Population of the United States: 1960 to

13 13 Percent Distribution of the Foreign-Born Population by Region of Birth, for the United States: 1960 to

14 14 M0501. Percent of People Who Are Foreign Born: 2007 Universe: Total population Data Set: 2007 American Community Survey 1-Year Estimates Source: American FactFinder ( 14

15 15 Selected Population Profiles Iterations for over 100 foreign-born groups For nation, states, and other geographic areas that have a total population of 500,000 and group population of 65,000 or more Additional social, economic, and demographic information on the foreign born not previously available from other ACS tables (e.g., fertility, disability, family income, poverty of individuals, etc.) 15

16 16 Select Sources That Include Data on the Foreign Born in the United States Population and Housing Decennial Censuses American Community Survey (ACS) Other Relevant Surveys 16

17 17 Decennial Census – Quick Facts Purpose: Apportionment of House seats among the states Universe: Entire U.S. resident population (households and group quarters) Frequency: Every 10 years (since 1790) Format: Short and long forms for Census 2000 but short form only for Census 2010 Geography:National and extensive sub-national 17

18 18 American Community Survey – Quick Facts Purpose: Provide timely data at national and extensive sub-national geography levels Universe: U.S. resident population (3 million housing units in sample) Frequency: Yearly estimates based on July 1 population Geography: Nation, state, county and, place (2005) and extensive sub-national (2008 forward) (65,000+ available now; 20,000+ in 3-year estimates available in December 2008; every geography down to block group level in 5-year estimates available in 2010) 18

19 19 American Community Survey – Key Migration Items In addition to all of the other items on the ACS: Place of birth/nativity (not country of citizenship) U.S. citizenship Year of naturalization (beginning in 2008 ACS) Year of entry Migration history (residence 1 year ago) Race, ethnicity (Hispanic origin), ancestry Language spoken at home 19

20 20 Comparing 2007 ACS Data to Census 2000 Data Global differences exist –e.g., residency rules, universes, reference periods For most population and housing subjects, comparisons can be made –Place of birth, citizenship, nativity, language can be compared –Year of entry can be compared (watch reference periods) –Residence 1 year ago (ACS) should not be compared to residence 5 years ago (Census 2000) How to Use the Data – Comparing ACS to Other Sources – 20

21 21 ACS Margin of Errors (MOEs) MOE describes the precision of an estimate at a given level of confidence Margin of Error = x Standard Error Census Bureaus statistical standard: 90 percent confidence level Users should conduct statistical testing to determine if two estimates are statistically different –This is especially important for small population groups because of large margins of error Data Users Handbook – 21
