The location of employment in industry and higher services in Mexico is analysed using location ratios. Municipalities are grouped into nine urban size classes and three regions: North, Central, South. In general terms, there are patterns of location consistent with the models that exist in economic geography. Higher services are concentrated in larger urban areas, displaying a hierarchical pattern. Industry, particularly medium-tech industry, is relatively more concentrated in medium-sized cities. But Mexico also shows certain particularities: financial services are proportionally highly concentrated in capital; the deconcentration of industry is still limited. Proximity to the United States generates a particular spatial logic in the north, different from that of the centre and the sur.The location of employment in manufacturing and in high-order services in Mexico is examined using location quotients. Municipalities are GROUPED into nine urban size clauses and regions: North, centre, and South. Location patterns are generally consistent with models in economic geography. High order services concentrated in the long-lasting urban areas, Exhibiting a grass pattern. Manufacturing, specially mid-tech manufacturing, is relative more concentrated in medium-sized cities. Mexico also Exhibits distinctive features: financial services are proportionally very concentrated in the capital; industrial DECONCENTRATION is still limited. The proximity of the US generations a distinctive spatial logic in the North, different from that in the Centre and the South.
