II. Rural Households

Rural Households refer to resident households in rural areas. Resident households in rural areas are the households residing for more than one year in the areas under the jurisdiction of administration of township governments (excluding county towns), and in the areas under the jurisdiction of administration of villages in county towns. Migrated households residing in the current addresses for over one year with their household registration in other places are included in the resident households of their current addresses. For households with their household registration in one place but all members of the households moving away for living in another place for over one year, they will not be included in the rural households of the area where they are registered, irrespective of whether they still keep their contracted land.

Resident Population refers to population staying at home permanently or for over 6 months during a year and sharing life economically with the household. Members of the household staying away from the household for over 6 months but keeping a close economic relation with the household by sending the majority of income to the household are regarded as resident population of the household. Government staff and workers or retirees living as close members of the household are also considered as resident population. However, servicemen, students of secondary technical schools or schools of higher education and persons with stable jobs and residence outside the household (excluding those visiting relatives or seeking medical service) are not included as resident population of the household. Resident population is used in calculating income, consumption, accumulation on per capita basis of rural households and in analyzing composition of rural households.

Semi labour force refers to persons capable of work, aged 16-17 and 51-60 for males and 16-17 and 46-55 for females. Persons at their working ages but not capable of work are not to be included as labour force. Persons not at working ages but participating regularly in work are included in semi labour force. For staff and workers as resident population of the household, they are included as full or semi labour force of the household if they are in the labour force.

Net income is mainly used as input for reproduction and as consumption expenditure of the year, and also used for savings and non-compulsory expenses of various forms.
