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.
