Description
Definition
This variable reflects the derive monthly income for the enumerated household
Universe
Every household at night between Wednesday 9 October and Thursday 10 October 1996.
Source of information
Derived fromindividual income, additional money generated and temittances received
Imputation and derivation
Derivation
Derived from census records for persons.
‘Derived household income’ was calculated by adding together all recorded individual incomes of household members, plus the household’s additional income and remittances received. Because individual income was recorded in intervals rather than exact amounts, an approximate amount had to be estimated for the calculations as follows:
• households claiming that they had no income were not adjusted,
• for the first class among those with incomes, the amount was R1 600,
• for the second class, the amount was the midpoint of the class interval,
• for the last class, the amount was R720 000,
• for the other classes, the amount was calculated as the logarithmic mean of the top and bottom of the
given interval.
If ‘Individual income’ was missing for a member of the household aged under 15, the income for the child was set to 0. However, if a member of the household aged 15 years or older had income missing, the ‘Derived household income’ was set to missing as there was insufficient information for the estimate to be reliable. If ‘Additional money generated’ or ‘Remittances received’ were missing, then they were set to 0. Income for the entire household were again converted into categories.

Notes
Warning: You should use this variable with caution and be aware of its limitations. Household income has been derived from personal incomes collected in ranges and additional money generated and remittance received. For each range, an assumption had to be made as to the appropriate point to use for the calculations. This has made the results tentative. Household income does not provide a measure of total income and its accuracy in representing relative income is unknown.
The relatively large proportion of households where one or more members did not specify their incomes needs to be noted. Cross tabulations indicate that they are evenly distributed by education and occupation. Care therefore needs to be taken when interpreting household incomes. Direct comparisons with other data sets cannot be made. The main reason for publishing the data is to show patterns and trends, rather then precise estimates.
