Classification

Within the 1990 State trial, PUMAs generally speaking follow the limitations of state communities, single areas, or census-defined “places”. If these markets go beyond 200,000 customers, these include divided in to as much PUMAs of 100,000+ owners as you can. None with the 1990 State trial PUMAs mix county outlines. Your 1990 Metro test, PUMAs typically follow the boundaries of whole main locations, city Statistical avenues, Primary Metropolitan Statistical locations, or non-metropolitan areas (read METAREA for descriptions among these terms and conditions). If these places go beyond 200,000 customers, they’ve been divided in to as much PUMAs of 100,000+ citizens that you can. 1990 Metro sample PUMAs often mix condition lines; when they would, STATEFIP and STATEICP rules are not available for households when it comes to those PUMAs. PUMAs in the 2000 census, 2010 census, plus the 2005-onward ACS/PRCS also consist of 100,000+ customers, and additionally they you should never cross condition outlines.

Observe that PUMA is state-dependent. The codes must be browse in combination with one of several CONDITION variables (STATEFIP or STATEICP). PUMAs is labeled by means (elizabeth.g., metropolitan, mixed metro/nonmetro, non-metropolitan) when you look at the varying PUMATYPE. PUMA is comparable to the district group variables, CNTYGP97 (1970) and CNTYGP98 (1980), plus the county financial neighborhood varying (ocean) for 1940 and 1950.

Note concerning Multi-Year Samples: The Census agency redraws PUMA boundaries every several years considering population records collected from the newest ples integrate new PUMAs within a few years of the Decennial Census. Notice comparability report to see which PUMAs utilized in each test. In Multi-Year ACS files https://datingperfect.net/dating-sites/twoo-reviews-comparison/, PUMA boundaries be determined by the initial seasons the respondent ended up being interviewed (discover MULTYEAR). Including in 2010-2012 3-year ACS test, participants from 2010 and 2011 match the Census 2000 situated PUMAs, while respondents from 2012 match the Census 2010 established PUMAs.

PUMA is actually a 5-digit numeric varying determining individuals utilize Microdata Area (PUMA) the spot where the homes device had been present. PUMAs are labeled by kind (elizabeth.g., metropolitan, blended metro/nonmetro, non-metropolitan) into the adjustable PUMATYPE. PUMA resembles the state group variables, CNTYGP97 (1970) and CNTYGP98 (1980), and also the condition financial Area changeable (SEA) for 1940 and 1950. PUMA particular variable requirements for lost, edited, or unknown findings, observations not relevant (N/A), observations not in market (NIU), top and bottom importance programming, etc. are supplied below by Census year (and data test if specified).

Consumer Note: PUMAs become pulled and coded differently the 1990 State and Metro samples. Within the 1990 county sample, PUMAs generally follow the limits of sets of areas, unmarried areas, or census-defined “places”. If such avenues exceed 200,000 customers, these are typically separated into as much PUMAs of 100,000+ people as you are able to. Not one on the 1990 county trial PUMAs cross county traces. From inside the 1990 Metro trial, PUMAs generally speaking stick to the limits of whole central towns, Metropolitan Statistical locations, Primary city Statistical Areas, or non-metropolitan areas (read METAREA for descriptions among these terminology). If these avenues surpass 200,000 customers, these are generally split into as many PUMAs of 100,000+ citizens as it can. 1990 Metro sample PUMAs occasionally get across state contours; if they perform, STATEFIP and STATEICP rules aren’t readily available for people in those PUMAs. PUMAs inside 2000 census, 2010 census, additionally the 2005-onward ACS/PRCS in addition consist of 100,000+ people, and so they dont mix condition lines.

User Note: PUMA is state-dependent, and so the rules needs to be browse in combination with among the many COUNTY variables: STATEFIP or STATEICP.

User mention: within the 2006-2011 ACS, individuals located in Louisiana PUMAs 01801, 01802, and 01905 had been all coded as surviving in Louisiana PUMA 77777. It is because these three PUMAs not any longer got adequate population are provided as individual entities because of the consequences of hurricane Katrina.

Comparability

This variable is certainly not similar across decades. PUMAs did not necessarily retain the same boundaries or PUMA rules between 1990 and 2000. The limits and PUMA requirements are exactly the same for the 2000 census together with 2005-2011 ACS/PRCS samples, with one distinguished exemption in Louisiana: as a result of population displacement after Hurricane Katrina, three PUMA’s (01801, 01802, and 01905) tend to be matched into code 77777 for the 2006-onward ACS and also for all matters when you look at the 2005-2007 ACS 3-Year file. They not had adequate society to get incorporated as different organizations.
