Codes and Frequencies
Most IPUMS data transformations are performed using variable harmonization tables that specify how each value in the source data is recoded. Some variables also require programming logic in addition to the harmonization table. The harmonization documents for this variable are:
HRSMAIN indicates the number of hours the respondent worked per week in jobs related to their primary occupation.
Comparability — Index
Comparability — General
The variable is conceptually comparable across samples, but there are some universe differences.
The variable is top-coded at 97 or more hours overall, but some samples have lower top codes.
Comparable information for work done outside the person's primary occupation can be found for some samples in the variable HRSADD. The total hours worked are reported for many samples in HRSWORK1 and HRSWORK2. For most people the work done in their main occupation equals their total hours of work.
Comparability — Brazil [top]
In contrast with the 1991 and 2001 samples, hours of work for household subsistence or production for own consumption are excluded in 2010.
Comparability — Costa Rica [top]
The question asked for the number of hours the person usually worked per week in his or her principal occupation.
Comparability — Indonesia [top]
The samples reports actual hours worked during the past week. For the 1980-1995 samples, persons who had a job but were temporarily absent from their primary job the week preceding the census are coded as "0" hours worked. Such persons are not in the universe for 1976. The 1980-1995 samples also contain data on total hours worked, found in HRSWRK1.
The census instructions for 1976 state that housemaids that work continuously in the household are counted as working 12 hours per day.
Comparability — Italy [top]
In 2001, the universe includes only persons 15+ who worked last week, while in 2011, it includes persons 15+ who were ever employed. Furthermore, the 2001 question asks how many hours a person actually worked in the week preceding the census, whereas the 2011 question asks for the usual number of hours worked. In 2001, if the respondent was absent from work the previous week due to vacation, illness, or some other form of leave, they were instructed to refer to their usual hours worked. In both years, respondents were instructed to include unpaid overtime work hours, and responses were top-coded at 71 hours.
Comparability — Nigeria [top]
The question asked for the number of hours per week in the main job for those who worked last week. The data for 2006-2008 samples is limited to those ages 10 and up who are economically active. The 2008 sample is top- coded at 90 hours per week.
Comparability — Panama [top]
The sample reports hours worked last week, not usual hours worked.
Comparability — Romania [top]
All samples report hours worked during the reference week (the week prior to the start of the census), not usual hours worked. There are minor universe changes between samples.
Comparability — United Kingdom [top]
The 2001 sample excluded persons older than 74 years from the question.
The 1991 sample is top-coded at 81 hours; 2001 is top-coded at 80 hours.
The 1991 sample combines 71 to 80 hours into a single category, coded in HRSMAIN to the 75.
Comparability — Uruguay [top]
The 2006 sample reports usual hours worked in the primary job.
