Data gathered in the survey include sources of income in cash and in kind and the level of consumption by item of expenditure. Related information such as family size, number of family members employed for pay or profit (wage/salary or own-account worker), occupation, age and educational attainment of household head, and housing characteristics were also included. The survey involved the interview of a national sample of about 41,000 sample households deemed sufficient to provide reliable estimates of income and expenditure levels for each province of the country, key cities and key municipalities. 1988-1994 are also available in an easy to use SDA format. The sample households covered in the survey were the same sample households interviewed in the July 1997 and January 1998 rounds of the Labor Force Survey (LFS). 2003, 2006, and 2009 are available from the Philippines Data Catalog.
