Description
Into the 1990 condition sample, PUMAs generally stick to the boundaries of district organizations, unmarried areas, or census-defined “places”. If these locations go beyond 200,000 owners, they might be divided in to as much PUMAs of 100,000+ people as you are able to. Not one associated with 1990 State test PUMAs cross state lines. When it comes down to 1990 Metro sample, PUMAs generally follow the borders of entire central metropolises, Metropolitan Statistical markets, biggest Metropolitan Statistical locations, or non-metropolitan areas (See METAREA for meanings among these terms and conditions). If these markets exceed 200,000 residents, they truly are split into as numerous PUMAs of 100,000+ residents as is possible. 1990 Metro sample PUMAs often get across county lines; if they would, STATEFIP and STATEICP codes aren’t designed for people in those PUMAs. PUMAs into the see it here 2000 census, 2010 census, additionally the 2005-onward ACS/PRCS also feature 100,000+ citizens, and they don’t cross state lines.
Observe that PUMA was state-dependent. The rules ought to be look over in combination with among STATE variables (STATEFIP or STATEICP). PUMAs include classified by type (elizabeth.g., metropolitan, combined metro/nonmetro, non-metropolitan) during the changeable PUMATYPE. PUMA resembles the state team variables, CNTYGP97 (1970) and CNTYGP98 (1980), and State financial location adjustable (ocean) for 1940 and 1950.
Note Regarding Multi-Year trials: The Census agency redraws PUMA boundaries every ten years centered on people ideas gathered from the newest ples incorporate the latest PUMAs within a few years associated with Decennial Census. Begin to see the comparability report to see which PUMAs are employed in each trial. In Multi-Year ACS documents, PUMA boundaries depend on the initial seasons the respondent was actually interviewed (discover MULTYEAR). Eg when you look at the 2010-2012 3-year ACS test, respondents from 2010 and 2011 match the Census 2000 created PUMAs, while respondents from 2012 match the Census 2010 situated PUMAs.
PUMA is actually a 5-digit numeric changeable distinguishing people incorporate Microdata neighborhood (PUMA) where in fact the property product ended up being present. PUMAs were categorized by means (elizabeth.g., metropolitan, combined metro/nonmetro, non-metropolitan) when you look at the changeable PUMATYPE. PUMA is comparable to the region people variables, CNTYGP97 (1970) and CNTYGP98 (1980), and the State Economic Area varying (water) for 1940 and 1950. PUMA particular variable codes for lacking, edited, or unknown findings, findings perhaps not appropriate (N/A), observations perhaps not in market (NIU), top and bottom value programming, etc. are supplied below by Census year (and information sample if given).
Consumer mention: PUMAs were pulled and coded in a different way for the 1990 State and Metro samples. In the 1990 State trial, PUMAs generally speaking stick to the boundaries of sets of areas, unmarried areas, or census-defined “places”. If such areas exceed 200,000 customers, they might be divided into as much PUMAs of 100,000+ residents as is possible. None from the 1990 State sample PUMAs cross county traces. For the 1990 Metro test, PUMAs generally speaking stick to the boundaries of entire main towns, city Statistical avenues, main city Statistical markets, or non-metropolitan places (discover METAREA for descriptions of those terms). If these locations meet or exceed 200,000 owners, these include divided in to as much PUMAs of 100,000+ citizens as you possibly can. 1990 Metro trial PUMAs sometimes get across state lines; if they do, STATEFIP and STATEICP requirements aren’t available for people in those PUMAs. PUMAs into the 2000 census, 2010 census, and 2005-onward ACS/PRCS additionally consist of 100,000+ residents, and they you should never get across state outlines.
Consumer mention: PUMA is actually state-dependent, meaning that the requirements ought to be see in conjunction with one of many CONDITION variables: STATEFIP or STATEICP.
User mention: In the 2006-2011 ACS, people located in Louisiana PUMAs 01801, 01802, and 01905 comprise all coded as located in Louisiana PUMA 77777. For the reason that these three PUMAs don’t have adequate people are incorporated as individual agencies because of the consequences of hurricane Katrina.
Comparability
This changeable is certainly not equivalent across ages. PUMAs decided not to necessarily wthhold the exact same limitations or PUMA codes between 1990 and 2000. The borders and PUMA rules are the same your 2000 census therefore the 2005-2011 ACS/PRCS examples, with one notable difference in Louisiana: because population displacement after Hurricane Katrina, three PUMA’s (01801, 01802, and 01905) were blended into laws 77777 when it comes to 2006-onward ACS and all situation during the 2005-2007 ACS 3-Year file. They no further got sufficient people to be incorporated as split agencies.
