Total time spent on secondary childcare of non-own, non-hh children


SCC_NOWNNHH is a 5-digit numeric variable ranging from 0 to 1440 minutes. Members of the dataset who are not ATUS respondents are assigned a value of 99999.


SCC_NOWNNHH reports the total amount of time during the diary day that the respondent spent in secondary childcare for non-own, non-household children under the age of 13.

This variable is calculated by summing the amount of time during each activity that the respondent reported having a non-own, non-household child in care.

Secondary childcare of non-household children is not recorded if the respondent's main activity is sleeping (0101xx), directly related to the care of household children (0301xx, 0302xx, 0303xx, 180301, 180302, 180303, or 180304), or directly related to the care of non-household children (0401xx, 0402xx, 0403xx, 180401, 180402, 180403, 180404).

Secondary childcare time total variables are available for other categories of children as well: all children (see SCC_ALL), household or own non-household children (see SCC_HHNHHOWN), own household children (see SCC_OWNHH, not available for 2003), own, non-household children (see SCC_OWNNHH, not available for 2003), non-own household children (see SCC_NOWNHH, not available for 2003), own children (see SCC_OWN, not available for 2003), and household children (see SCC_HH, not available for 2003).

Users can also apply a secondary child care filter in the extract builder when creating time use variables. Distinctions are available for the following groups:

  • All children
  • Household or own non-household children
  • Own household children (not available for 2003)
  • Own, non-household children (not available for 2003)
  • Non-own household children (not available for 2003)
  • Non-own, non-household children


This variable is comparable across years.
