title: American Community Survey, 2005: 1-year Public Use Microdata Sample

description: &lt;p&gt;The American Community Survey (ACS) is a part of the Decennial Census Program, and is designed to produce critical information about the characteristics of local communities. The ACS publishes social, housing, and economic characteristics for demographic groups covering a broad spectrum of geographic areas in the United States and Puerto Rico. Every year the ACS supports the release of single-year estimates for geographic areas with populations of 65,000 or more. Demographic variables include sex, age, relationship, households by type, race, and Hispanic origin. Social characteristics variables include school enrollment, educational attainment, marital status, fertility, grandparents caring for children, veteran status, disability status, residence one year ago, place of birth, U.S. citizenship status, year of entry, world region of birth of foreign born, language spoken at home, and ancestry. Variables focusing on economic characteristics include employment status, commuting to work, occupation, industry, class of worker, income and benefits, and poverty status. Variables focusing on housing characteristics include occupancy, units in structure, year structure built, number of rooms, number of bedrooms, housing tenure, year householder moved into unit, vehicles available, house heating fuel, utility costs, occupants per room, housing value, and mortgage status. The American Community Survey is conducted under the authority of Title 13, United States Code, Sections 141 and 193, and response is mandatory. (Source: ICPSR, retrieved 06/29/2011)&lt;/p&gt;

description: collection_notes: The 2005 PUMS was designed to have a one-percent sample of the housing unit universe in the United States, District of Columbia, and Puerto Rico. For determining the PUMS
 sample size, the size of the housing unit universe is the ACS estimates of the total number of housing units. (See table on p. 2 of accuract05_oct06.pdf) 
 The PUMS sample was selected using a systematic sampling method with sampling intervals chosen to yield the sample sizes that are given in Table 1 for each state. The sampling
 interval for each state is the ratio of the number of housing unit records available for sampling and the required sample size (sampling intervals are not rounded to integers). The
 sampling is performed on the ACS housing unit sample. All persons in housing units selected for PUMS are included in the PUMS person sample.
 The sampling of housing units was performed as follows.
 1. The housing units were sorted by ACS estimation area, PUMA, interview mode, tenure, building type, household type, race and Hispanic origin of the householder, age of the
 householder, county, tract, and housing unit weight.
 2. A random number between zero and the sampling interval was chosen to initialize a counter.
 3. At each record, the value of the counter is incremented by one and compared to the sampling interval
 a. If the counter’s new value is greater than the sampling interval, the record is selected for the PUMS. The counter is decreased by the sampling interval with the new value
 passed to the next record.
 b. If the counter is less than the sampling interval, the record is not selected for the PUMS and the value of the counter is passed to the next record without altering its value.

Collection mode varied; CAPI and CATI phases followed mailings.
