Time spent during activity on secondary child care of non-own, household children


SCC_NOWNHH_LN is a 4-digit numeric variable reported in minutes. Values for ATUS respondents range from 0 to 1440 minutes. Members of the dataset who are not ATUS respondents are assigned a value of 99999 = NIU (Not in universe).


SCC_NOWNHH_LN reports the amount of time during the associated activity that the respondent reported engaging in secondary childcare for non-own, household children under the age of 13.

Secondary childcare of household children is not recorded if the respondent's main activity is sleeping (0101xx) or directly related to the care of household children (0301xx, 0301xx, 0303xx, 180301, 180302, 180303, or 180304). Secondary childcare is not recorded if all household children are asleep, but may be recorded for part of an activity if a child wakes up or goes to bed during the activity.

For each respondent, all values of SCC_NOWNHH_LN are summed to create SCC_NOWNHH.

SCC_NOWNHH_LN is available only if you select a hierarchical extract. If you request a hierarchical extract and plan to construct time use variables in your statistics package, this variable may be useful to you. If you request a rectangular extract and plan to construct time use variables through the extract system, SCC_NOWNHH_LN will not be included in your extract, as persons are the unit of observation for rectangular extracts rather than activity or who records.
