ACREPROP
Acreage of property

Description

ACREPROP indicates the number of acres (for U.S. census samples) or cuerdas (for Puerto Rican census samples) on which a housing unit was located.

In the U.S. census samples from 1960-1970 and the 1980 Puerto Rican census sample, ACREPROP can be used to identify city and suburban lots. In the U.S. census samples from 1980-2000 and the 2000 Puerto Rican census sample, it can be used to identify all lots on less than 1 acre. The 1990 Puerto Rican sample identifies neither city and suburban lots nor lots on less than 1 acre.

In 1960, not all households received this question, and only households outside cities with 50,000+ residents in the IPUMS include the question. Such cases accurately represent proportional distributions but not correct absolute numbers. See SAMP1960 for instructions on making appropriate corrections to derive absolute numbers for the total population outside cities with 50,000+ residents.

Users Note
The traditional unit of land area in Puerto Rico is the cuerda. The cuerda is equal to about 3930 square meters, 4700 square yards, or 0.971 acres. Because the cuerda and the acre are so close to being equal, they are often treated informally as being equal. Mainlanders sometimes call the unit the "Spanish Acre." The IPUMS has preserved the units for the mainland U.S. as acres and Puerto Rico as cuerdas.

Comparability

The Census Bureau used this variable, in conjunction with others, to identify farms (see FARM). Properties in cities of 50,000+ are categorized as "N/A" in 1960 and are defined as city lots in other years.

Universe differences aside, the categories are basically consistent for the 1960-1970 U.S. census samples as well as for the 1980, 1990 and 2000 U.S. census samples and the 2000 Puerto Rican sample. There are, however, substantial measurement differences between the 1980 and 1990 Puerto Rican samples and the remaining samples. The most consistently identified category is rural lots of 10+ acres (or 10+ cuerdas, Puerto Rico), which is identified in all but the 1980 Puerto Rico sample (this is code "8").
