The Data: Coverage, Periodicity, and Timeliness
Coverage characteristics	Data are disseminated on the Volume of Production Index (VoPI) (1994=100), which is derived from the Value of Production Index (VaPI) and the Producer's Price Index (PPI). The VoPI is based on the manufacturing industry groups under the 3-digit (sectoral) level of the 1994 Philippine Standard Industrial Classification (PSIC). The Value of Production Index (VaPI, 1994=100) is a chained Laspeyres index with fixed base weight of the value of goods produced by sample manufacturing establishments covered in the Monthly Integrated Survey of Selected Industries (MISSI), previously known as the Survey of Key Enterprises in Manufacturing (SKEM). The weights used for the index at the 3-digit (sectoral) and 4-digit (sub-sectoral) level of the 1994 PSIC are based on the 1994 Census of Establishments (CE). For 2002, the VaPI covers manufacturing establishments representing 5 percent of the total manufacturing establishments which have an average total employment of 20 or more. Almost 50 percent of the sample is located in Metropolitan Manila. The PPI is used to deflate the VAPI to derive the VOPI. The data are not seasonally adjusted.
Periodicity	Monthly.
Timeliness	8 weeks after the reference month. (See Notes.)
