For the 1990 State sample, PUMAs usually stick to the boundaries of district organizations, unmarried counties, or census-defined “places”. If these markets go beyond 200,000 owners, they might be separated into as many PUMAs of 100,000+ people as you possibly can. Not one on the 1990 State sample PUMAs cross county traces. For any 1990 Metro trial, PUMAs generally proceed with the borders of whole main urban centers, Metropolitan Statistical avenues, biggest city Statistical locations, or non-metropolitan places (See METAREA for meanings of those conditions). If these markets exceed 200,000 customers, they are split into as many PUMAs of 100,000+ citizens as is possible. 1990 Metro sample PUMAs occasionally cross condition outlines; when they create, STATEFIP and STATEICP requirements commonly readily available for people when it comes to those PUMAs. PUMAs into the 2000 census, 2010 census, as well as the 2005-onward ACS/PRCS also consist of 100,000+ owners, in addition they try not to get across state lines.
Keep in mind that PUMA is actually state-dependent. The rules ought to be study in conjunction with the CONDITION variables (STATEFIP or STATEICP). PUMAs were labeled by sort (elizabeth.g., metropolitan, combined metro/nonmetro, non-metropolitan) in the changeable PUMATYPE. PUMA resembles the state class variables, CNTYGP97 (1970) and CNTYGP98 (1980), as well as the condition Economic neighborhood varying (SEA) for 1940 and 1950.
Note relating to Multi-Year examples: The Census agency redraws PUMA boundaries every several years considering populace details obtained from the newest ples include new PUMAs within a few years of Decennial Census. Understand comparability report to see which PUMAs are employed in each sample. In Multi-Year ACS records, PUMA boundaries be determined by the initial 12 months the respondent was questioned (see MULTYEAR). For instance within the 2010-2012 3-year ACS test, participants from 2010 and 2011 correspond to the Census 2000 dependent PUMAs, while participants from 2012 correspond to the Census 2010 based PUMAs.
PUMA are a 5-digit numeric adjustable identifying individuals need Microdata neighborhood (PUMA) where in fact the property product got set. PUMAs were categorized by means (elizabeth.g., metropolitan, mixed metro/nonmetro, non-metropolitan) for the changeable PUMATYPE. PUMA is much like the county party variables, CNTYGP97 (1970) and CNTYGP98 (1980), and also the county business location variable (SEA) for 1940 and 1950. PUMA specific variable requirements for lacking, edited, or unknown observations, observations maybe not applicable (N/A), findings not in universe (NIU), leading and bottom importance programming, etc. are provided below by Census season (and data sample if given).
Individual notice: PUMAs become pulled and coded differently for all the 1990 condition and Metro trials. Within the 1990 condition trial, PUMAs usually stick to the boundaries of groups of areas, unmarried areas, or census-defined “places”. If this type of markets go beyond 200,000 residents, they are split into as much PUMAs of 100,000+ citizens as is possible. Not one associated with the 1990 county trial PUMAs mix county traces. During the 1990 Metro test, PUMAs normally follow the limitations of entire central cities, city Statistical avenues, main Metropolitan Statistical Places, or non-metropolitan areas (discover METAREA for descriptions of those terms and conditions). If these places go beyond 200,000 residents, these are generally split into as much PUMAs of 100,000+ citizens possible. 1990 Metro sample PUMAs often get across condition traces; whenever they perform, STATEFIP and STATEICP codes commonly designed for families in those PUMAs. PUMAs in the 2000 census, 2010 census, together with 2005-onward ACS/PRCS also feature 100,000+ citizens, and they do not get across county traces.
Consumer notice: PUMA is actually state-dependent, therefore the rules needs to be look over in conjunction with among STATE variables: STATEFIP or STATEICP.
Individual mention: For The 2006-2011 ACS, people surviving in Louisiana PUMAs 01801, 01802, and 01905 comprise all coded as residing in Louisiana PUMA 77777. It is because these three PUMAs don’t had sufficient inhabitants getting included as different organizations due the results of hurricane Katrina.
This changeable isn’t similar across ages. PUMAs decided not to always retain the same boundaries or PUMA requirements between 1990 and 2000. The limits and PUMA requirements are exactly the same when it comes to 2000 census additionally the 2005-2011 ACS/PRCS samples, with one noteworthy exception in Louisiana: because populace displacement following Hurricane Katrina, three PUMA’s (01801, 01802, and 01905) is matched into rule 77777 when it comes to 2006-onward ACS and all problems into the 2005-2007 ACS 3-Year file. They no more had sufficient population to get provided as split agencies.
