This is a 3-digit numeric variable.

Description

AGE reports the age of respondents.

When age is recorded in categories, a mid-point of each age group is assigned, for example, 17 for age group 15-19. When surveys only included the year of birth of respondents, AGE was computed by subtracting the year of birth from the year of the survey. To protect the anonymity of the oldest respondents, age is topcoded. Users should note differences in topcodes across countries and years.

In 2005 and 2010, AGE is not an exact measure of a diarist's age. The original variable data indicates the respondent's age in 15 categories, and is recoded in the following way:

AGEGR5 - AGE (recoded)
15 to 17 - 16
18 to 19 - 18
20 to 24 - 22
25 to 29 - 27
30 to 34 - 32
35 to 39 - 37
40 to 44 - 42
45 to 49 - 47
50 to 54 - 52
55 to 59 - 57
60 to 64 - 62
65 to 69 - 67
70 to 74 - 72
75 to 79 - 77
80 years and over - 80

In 2015, the original variable age captures the respondent's age in 7 interval categories, and is recoded at the middle point.

For 2000 and 2005, age at the time of the survey is not available though year and month of birth are available. AGE is the difference between the survey year and birth year.

Comparability — United States [top]

For 1998-2001, the 1999-2001 NSP survey did not initially ask the respondent's age. The survey team did, however, try to recontact participants to ask for their ages; 387 individuals could not be located or did not reply.
