Detailed results tables are presented from an unweighted statistical analysis of selected portions of the 1992-94 National Human Activity Pattern Survey (NHAPS) data base. This survey collected data on the potential exposure of Americans to important houshold pollutants. Randomly selected individuals (9,386) supplied minute-by-minute diaries spanning a 24-hour day as well as follow-up questions on specific exposure types. Selected 24-hour diary locations and activities, selected regroupings of the 24-hour diary locations, activities, and smoker-present categories, and most of the follow-up question variables in the NHAPS data base were statistically analyzed across 12 subgroups (gender, age, Hispanic, education, employment, census region, day-of-week, season, asthma, angina and bronchitis/emphysema). Overall statistics were also generated for the 9,386 total respondents. Tables show descriptive statistics (including frequency distributions) of time spent and frequency of occurrence in each of 39 locations and for 22 activities (that were experienced by more than 50 respondents), along with equivalent tables for 10 regrouped locations (Residence-Indoors, Residence-Outdoors, Inside Vehicle, Near Vehicle, Other Outdoor, Office/Factory, Mall/Store, Public Building, Bar/Restaurant, Other Indoor), seven regrouped activities (No Exposure, Food Preparation, Laundry/Dishes, Housekeeping, Bathing/Washing, Yardwork/Maintenance, Sports/Exercise, Eating/Drinking), and Smoker Present. Tables of frequency distributions of time spent in exposure activities, or the frequency of occurrence of exposure activities, as determined from the follow up questions that were analyzed are also presented. Detailed indices provide page numbers for each table. An Appendix contains a condensed listing of the questionnaires (Versions A and B for adults, child-direct and child-proxy interview types), including the question number, the NHAPS data base variable name, and the verbatim question text.
