In 1990 county sample, PUMAs typically follow the boundaries of region groups, solitary counties, or census-defined «places». If these avenues go beyond 200,000 people, they’re separated universitydatings price into as many PUMAs of 100,000+ owners as it can. Not one associated with 1990 State test PUMAs get across county contours. When it comes to 1990 Metro test, PUMAs generally proceed with the limits of whole central metropolitan areas, Metropolitan Statistical markets, biggest city Statistical segments, or non-metropolitan areas (See METAREA for meanings of those terminology). If these avenues meet or exceed 200,000 citizens, these are generally divided in to as numerous PUMAs of 100,000+ people as possible. 1990 Metro trial PUMAs often mix county lines; once they perform, STATEFIP and STATEICP rules aren’t readily available for households in those PUMAs. PUMAs during the 2000 census, 2010 census, together with 2005-onward ACS/PRCS in addition contain 100,000+ people, and try not to get across state contours.

Remember that PUMA is state-dependent. The rules ought to be browse in conjunction with among the many STATE variables (STATEFIP or STATEICP). PUMAs become classified by kind (elizabeth.g., metropolitan, blended metro/nonmetro, non-metropolitan) within the changeable PUMATYPE. PUMA is similar to the state people variables, CNTYGP97 (1970) and CNTYGP98 (1980), plus the county Economic room variable (ocean) for 1940 and 1950.

Note With regards to Multi-Year trials: The Census Bureau redraws PUMA boundaries every 10 years based on people suggestions gathered from most recent ples incorporate the PUMAs within a couple of years of Decennial Census. Notice comparability statement to determine what PUMAs are utilized in each test. In Multi-Year ACS records, PUMA boundaries be determined by the original 12 months the respondent had been questioned (see MULTYEAR). Like inside the 2010-2012 3-year ACS sample, respondents from 2010 and 2011 correspond to the Census 2000 oriented PUMAs, while participants from 2012 correspond to the Census 2010 depending PUMAs.

PUMA are a 5-digit numeric adjustable determining people utilize Microdata location (PUMA) in which the homes device is found. PUMAs become categorized by means (e.g., metropolitan, mixed metro/nonmetro, non-metropolitan) within the variable PUMATYPE. PUMA is comparable to the state group variables, CNTYGP97 (1970) and CNTYGP98 (1980), while the condition Economic room changeable (ocean) for 1940 and 1950. PUMA specific adjustable rules for lost, modified, or unidentified findings, observations perhaps not applicable (N/A), findings not in world (NIU), leading and bottom part advantages programming, etc. are supplied below by Census 12 months (and facts test if given).

User notice: PUMAs is driven and coded in different ways for 1990 State and Metro products. For the 1990 condition sample, PUMAs normally follow the limitations of categories of counties, unmarried areas, or census-defined «places». If such segments go beyond 200,000 owners, they’re divided in to as numerous PUMAs of 100,000+ customers as is possible. Nothing regarding the 1990 county sample PUMAs get across state lines. In 1990 Metro sample, PUMAs generally speaking follow the limitations of entire central towns and cities, city Statistical Places, Primary city Statistical segments, or non-metropolitan places (See METAREA for meanings among these terms and conditions). If these segments meet or exceed 200,000 citizens, they’ve been divided into as numerous PUMAs of 100,000+ customers possible. 1990 Metro trial PUMAs occasionally mix county outlines; if they manage, STATEFIP and STATEICP codes commonly readily available for families in those PUMAs. PUMAs from inside the 2000 census, 2010 census, therefore the 2005-onward ACS/PRCS additionally feature 100,000+ customers, as well as cannot cross state lines.

Consumer mention: PUMA are state-dependent, and so the requirements need to be see in combination with one of the STATE variables: STATEFIP or STATEICP.

User mention: For The 2006-2011 ACS, individuals staying in Louisiana PUMAs 01801, 01802, and 01905 happened to be all coded as living in Louisiana PUMA 77777. It is because these three PUMAs no longer got sufficient populace becoming provided as separate entities due the results of hurricane Katrina.


This changeable isn’t equivalent across ages. PUMAs failed to fundamentally wthhold the exact same boundaries or PUMA requirements between 1990 and 2000. The limitations and PUMA rules are the same your 2000 census and 2005-2011 ACS/PRCS trials, with one distinguished difference in Louisiana: due to inhabitants displacement appropriate Hurricane Katrina, three PUMA’s (01801, 01802, and 01905) are matched into signal 77777 when it comes down to 2006-onward ACS and also for all cases in the 2005-2007 ACS 3-Year document. They no longer had enough society becoming integrated as different organizations.
