|Title||What is the coverage and sample size of the Household Income and Expenditure Survey (HIES)?|
The HIES collects information on a sample of about 8,700 households selected from households with 1 or more persons in Korea as of 2010. Households whose income and expenditure cannot be determined are excluded:
- Agriculture/Forestry/Fishery (AFF) households
- Foreigner households
- Households whose financial balance cannot be obtained continuously
- Households operating business (i.e. home stay, restaurant and accommodation) at residence, and thus whose business cost and household expenditure cannot be distinguished
- Households of non-blood ties.
