Follows the recommendation of the BLS, consistent with the ILO Consumer Price Index Manual.

The sample consists of households in metropolitan area with 1-5 people and 12,000-62,000 baht/month in Bangkok and its suburban areas and all four regions of Thailand, covering 43 of 77 provinces.

Level of detail for commodities and services are sufficient for detailed analysis of price movement. The classification system was developed by the Bureau of Trade and Economic Indices (BTEI) corresponding to the household expenditure survey conducted by National Statistics Office (NSO) which is consistent with the UN COICOP classification. The variation used by Thailand has seven divisions, 29 groups and 53 subgroups.

Attributes by base year:

• Base year 2002
• Base year 2007
• Base year 2011 - 450 items, 10,000-60,000 baht
• Base year 2015 - 422 items including the seven essential categories listed below.

Categories:

• Food and non-alcoholic beverages
• Apparel and footwear
• Housing and furnishing
• Transportation and communication
• Recreation and reading
• Tobacco and alcoholic beverages

Geographic coverage:

• Bangkok metropolitan area - four provinces
• Central region - 11 provinces
• Northern region - 9 provinces
• Northeastern region - 10 provinces
• Southern region - 9 provinces
