HHLDSIZE reports the total number of household members.

There are cases where household size is not presented directly or in full. In such cases, this variable is calculated based on information that is available.

In 1979, there are numerous instances in the original data of the household size variable being inconsistent with other variables. This was addressed in three ways. (1) The original household size variable does not seem to include the respondent when he is under the age of 18. Therefore, if the respondent is under the age of 18 household size is increased by one. (2) Upon doing this, there were still inconsistencies which were fixed by adding the original count variable for total household children under the age of 18 to household size. For example, if in the original data household size is one and the respondent is a single parent then the total number of his or her children is added to household size. (3) These two steps addressed the majority of the issues with household size, however, a few problems still remained. For example, several diarists responded that they were married without children but listed their household size as one. We address this issue by increasing the household size until it's logically consistent with the other variables. For example, in the previous example the household size is increased from one to two so as to account for the fact that the respondent is married. Please note that this affects a very small number of cases.

In 1985, there are a few households where the number of children is equivalent to the household size. In cases where households contain three or more individuals under 18 living without an adult, the original HHLDSIZE variable is incremented by one.

In 1975, there are seven cases where the number of adults is reported and include no children aged under 5, but the number of older children is missing. In these cases, household size is set to the number of adults.
