MIGRATE1
Migration status, 1 year

Description

MIGRATE1 reports whether the person had changed residence since a reference point 1 year ago. Specifically, individuals age 1+ were asked if they had lived in the "same house" (non-movers) or a "different house" (movers) one year earlier. Persons who had moved were to indicate the foreign country or the state, county, and place of their normal residence during the reference year. Migration data were collected only for sample-line persons in 1950.

The category "Same house" includes all eligible persons who did not move since the reference year, as well as those who had moved but by the enumeration or survey date had returned to their earlier residence. The category "Different house" includes persons who lived in a different house in the reference year. For 1950, movers (those who reported living in a different house in the reference year) are further subdivided according to type of move (e.g., within the county or across state lines). The ACS and the PRCS report only same/different residence and identifies those previously living abroad.

Therefore, for the ACS/PRCS samples, MIGRATE1 uses information contained in the IPUMS variable MIGPLAC1 and compatible PUMAs of migration and PUMAs of residence to indicate whether movers migrated between states or within the same state (the same levels of detail in the 1950 classification.). For movers who migrated between states, a detailed version of MIGRATE1 indicates whether they moved between contiguous or non-contiguous states. For movers who migrated within the same state, detailed MIGRATE1 indicates whether they moved within or between PUMAs.

Editing Procedure


MIGRATE1 (Migration status, 1 year) MIGPUMA1 (PUMA of residence 1 year ago) MIGPLAC1 (State of country of residence 1 year ago)

ACS Years: 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015

ACS editing procedure:

Migration status

If migration status (MIGRATE1) is "Same as person 1" (an option on CATI/CAPI), MIGRATE1 and MIGPUMA1 and MIGPLAC1 will be replaced with the values from person 1. If there is no person 1, MIGRATE1 will be replaced with a missing value. Starting in 2008, if person 1 has this response, MIGRATE1 and MIGPUMA1 and MIGPLAC1 will be replaced with the values from the first person in the household with either "No, outside the United States and Puerto Rico" or "No, different house in the United States or Puerto Rico" for MIGRATE1.

If a person is under 1 year old, MIGRATE1 will be replaced with "Not in universe."

If a person is 1 or older, reports their migration status as "Not reported" "Person is under year old" "No, outside the U.S." or "No, unspecified" and MIGPLAC1 is a U.S. state, MIGRATE1 will be replaced with "No, different house in the U.S." If MIGPLAC1 is Puerto Rico, MIGRATE1 will be replaced with "No, different house in Puerto Rico or the U.S."

If a person is 1 or older, reports their migration status as "Not reported" "Person is under year old" "No, different house in the U.S." or "No, unspecified", current state of residence is in the U.S., and MIGPLAC1 is outside the U.S., MIGRATE1 will be replaced with "No, outside the U.S." If a person is 1 or older, reports their migration status as "Not reported" "Person is under year old" "No, different house in Puerto Rico or the U.S." or "No, unspecified", current state of residence is Puerto Rico., and MIGPLAC1 is outside the U.S., MIGRATE1 will be replaced with "No, outside Puerto Rico or the U.S."

If a person is 1 or older, reports their migration status as "Person is under year old" or "No, unspecified" and MIGPLAC1 is not reported, MIGRATE1 will be replaced with "Not reported."

If a person is 1 or older, does not report a value for MIGRATE1 or MIGPLAC1, is the reference person or their spouse, and MOVEDIN indicates they moved in the past 12 months, MIGRATE1 will be replaced with "No, different house in the United States." If MOVEDIN was not within the past year, but there is a spouse or a son/daughter (aged 1-18) with a value of MIGRATE1, that value will be assigned to the reference person or the spouse. For the reference person - if MIGRATE1 is still missing, it will be allocated from another reference person with a similar value for RACE, AGE, EMPSTAT, EDUC, and METRO. For the spouse of the reference person - if MIGRATE1 is still missing, it will be replaced with the reference person's value.

If a person is between 1 and 18, does not report a value for MIGRATE1 or MIGPLAC1, is the child of the reference person, and MOVEDIN indicates they moved in the past 12 months, MIGRATE1 will be replaced with "No, different house in the United States." If MOVEDIN was not within the past year, but there is a female spouse of the reference person with a value of MIGRATE1, that value will be assigned to the child of the reference person. If there is not a female spouse of the reference person, MIGRATE1 will be replaced with the reference person's value.

For a person who is 1 or older, is not the spouse or child (age 18 and under) of the reference person, and does not report a value for MIGRATE1 or MIGPLAC1, MIGRATE1 will be allocated from another person with a similar value for RACE, AGE, EMPSTAT, EDUC, and METRO.

Migration state and PUMA

If a person is not in universe for MIGRATE1, they are also not in universe for MIGPUMA1 and

MIGPLAC1.

If the reference person does not report a value for MIGPLAC1 or MIGPUMA1 and there is a spouse or child (age 1-18) in the household with the same value as the reference person for MIGRATE1 who has a value for MIGPLAC1 or MIGPUMA1, that value will be assigned to the reference person. If the value is still missing it will be allocated. For those who report moving from within the U.S., the allocated value will be drawn from another person with a similar value for MIGRATE1, BPL, RACE, AGE, EMPSTAT, EDUC, and METRO. For those who report moving from outside the U.S., the allocated value will be drawn from another person with a similar value for MIGRATE1, HISPAN, RACE, AGE, and EMPSTAT.

If the spouse of the reference person does not report a value for MIGPLAC1 or MIGPUMA1 but the reference person does and has the same value for MIGRATE1 as the spouse, the reference person's value of MIGPLAC1 and MIGPUMA1 value will be assigned to the spouse of the reference person. If there is a child of the reference person who is 1-18 with the same value of MIGRATE1 as the spouse, their values of MIGPLAC1 and MIGPUMA1 will be assigned to the spouse of the reference person. If MIGPLAC1 and MIGPUMA1 are still missing, they will be allocated. For those who report moving from outside the U.S., the allocated value will be drawn from another person with a similar value for MIGRATE1, HISPAN, RACE, AGE, and EMPSTAT. For those who report moving from within the U.S., the allocated value will be drawn from another person with a similar value for MIGRATE1, BPL, RACE, AGE, EMPSTAT, EDUC, and METRO.

If the child (age 1-18) of the reference person does not report a value for MIGPLAC1 or MIGPUMA1 but the reference person, the reference person's spouse, or another child of the reference person does, and has this person has same value for MIGRATE1 as the child, this person's value of MIGPLAC1 and MIGPUMA1 will be assigned to the child of the reference person. If MIGPLAC1 and MIGPUMA1 are still missing, they will be allocated. For those who report moving from outside the U.S., the allocated value will be drawn from another person with a similar value for MIGRATE1, HISPAN, RACE, AGE, and EMPSTAT. For those who report moving from within the U.S., the allocated value will be drawn from another person with a similar value for MIGRATE1, BPL, RACE, AGE, EMPSTAT, EDUC, and METRO.

For a person who is 1 or older, is not the spouse or child (age 18 and under) of the reference person, and does not report a value for MIGPLAC1 or MIGPUMA1, it will be allocated. For those who report moving from outside the U.S., the allocated value will be drawn from another person with a similar value for MIGRATE1, HISPAN, RACE, AGE, and EMPSTAT. For those who report moving from within the U.S., the allocated value will be drawn from another person with a similar value for MIGRATE1, BPL, RACE, AGE, EMPSTAT, EDUC, and METRO.

The same logic outlines in the steps above also applies when a person leaves the U.S. state they migrated from unspecified. If the immigrated from abroad, if no relative has a value for MIGPLAC1, a person's reported place of birth (BPL) will be assigned for MIGPLAC1. If that step fails, then the value be allocated.

The same steps also apply to disentangle the minor civil divisions within New York City or when other smaller geographic areas are not reported (small geographic areas are not publicly available in PUMS data).
