Adjustment of the Regional Indicator of Income in Retail Trade

Alberto Padilla

No 2018-17, Working Papers from Banco de México

Abstract: INEGI publishes, on a monthly basis, national indexes for sector, subsector and industry group of wholesale and retail trade, and state indexes for commerce sector based on information from the Monthly Survey of Commercial Establishments, EMEC. Although the sample design of this survey is representative at the national level and by industry group of economic activity of the commerce sector, the aggregation of state indexes at industry group level, necessary to construct regional indicators, requires an adjustment in the weighting of the observations. This document presents an aggregation methodology to build regional indexes based on retail trade state income data calculated from the information of EMEC databases. Moreover, a measure of the relative size of real income by region is proposed, it identifies those subsectors of retail trade with greatest contribution to the growth of regional income.
