3.8 History of survey and data changes
Family income distribution survey was conducted for the first time in 1964. It was a sampling survey of family income/expenditure conducted by DGBAS. In 1966, the BAS office of the provincial government took over and began conducting the survey every other year. In 1970, Taipei city was upgraded to a city directly administered by the Cabinet. Since then, the BAS offices of the provincial government and Taipei city conducted the survey separately. The survey was then conducted yearly. In 1979, Kaohsiung was upgraded to a state-governed city. The BAS offices of the provincial government, Taipei city and Kaohsiung city now conducted the survey separately once yearly. In 2000, the provincial government was downsized and the BAS office of the provincial government was turned into the Central Taiwan Office of DGBAS. Since then, the survey has been conducted separately by DGBAS Central Taiwan Office and the BAS offices of Taipei and Kaohsiung cities yearly.

5. Data quality
5.1 Explanations for statistical methodology, data manipulation and data source:
1. Family income/expenditure surveys are conducted using registered household data with the county/city for the general population. Stratified 2-Stage Random Sampling is used to select those to be interviewed. The employed population is divided by the village/neighborhood into 3 strata -- Urban, City and Country (Taipei city and Kaohsiung city excepted) -- according to percentages of industries. The Stage 1 sampling unit is the village/neighborhood and the Stage 2 the household. These households are interviewed once a year. Major annual income/expenditure items are in the survey. The number of households is weighted to obtain desired data. The household weight is obtained by multiplying the number of households interviewed by the number of all households of the population.
2. Refer to “Taiwan Family Income/Expenditure Survey” for the survey method and the sampling method.
5.2 Cross-checking mechanism to ensure data reasonableness:
Extreme values of income and expenditure accounts are prepared and cross-checked. The results are classified by region, degree of urbanization and occupation to ensure accuracy.
