(a) “HASALL (1982-2016)”: This file contains the full array of responses from the 34 years of surveys, including both the basic random surveys and the additional “oversample” surveys. The “oversample” interviews were conducted each year from 1994 through 2012, with the one exception of 1996, to enlarge the samples of Anglo, African-American, and Hispanic respondents to about 500 each. It also includes the additional surveys conducted in 1995, 2002 and 2011 with large representative samples of Houston's Asian communities, with one-fourth of the interviews conducted in Vietnamese, Mandarin, Cantonese, or Korean). From 2013 through 2016, the surveys reached larger basic samples, making it unnecessary to conduct additional oversample interviews.These are the data that enable the project to analyze the continuities and changes that have been occurring over the course of more than three decades among Harris County residents.

(b) “HASCENSUS (2003-2015)”: This data file is available only to research scholars by special request. It contains additional detailed information from the U.S. Census on the characteristics of the respondents’ neighborhoods, down to the block-group level. The data include—at the level of county, PUMA, ZCTA, census tract and block group—the population and geographical size of the neighborhood, the distributions by ethnicity and nativity, the age and gender composition, the employment and commuting patterns, and the levels of education, income and home-ownership. With this information linked to the 2003-2014 Houston Area Survey data, researchers are able to connect the respondents’ perceptions and experiences with the characteristics of the neighborhoods in which they live, thereby adding an important contextual dimension to analyses of the factors that predict individual differences in attitudes and beliefs.
