            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. In 2011,
some counties were upgraded to special municipality. In 2012, due to the adjustment of government organization, DGBAS, New Taipei City, Taipei city, Taichung City, Tainan City and Kaohsiung city conducted the survey separately once yearly. In 2014, Taoyuan City was upgraded to special municipality, and also conducted the survey separately once yearly.

     *Statistical Methodology and Source Data:

(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 appropriate stratum is determined by employment structure in industry and education level. The Stage 1 sampling unit is the village/neighborhood and the Stage 2 the household. The survey is conducted through interview, leave-out/pick-up questionnaire, on-line Internet questionnaire, and so on. 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.
