Indonesia practices calculating regional and national income accounts on a quarterly and yearly basis through national and regional consultation meetings. There are often discrepancies between national aggregates and regional sums, as well as between production and expenditure approaches. Sources of discrepancies include differences between national and provincial inflation data and data collection methods. Problems include differences in data sources between national and regional levels and data gaps, particularly in services sector data. Efforts are made to reconcile data and identify sources of discrepancies through comparative analysis of raw data and methodology discussions. Plans are underway to shift calculations to income approaches, implement SNA 2008 and ISIC rev.4 standards, and use the 2006 Economic Census as a benchmark.
