The Great Regional Industry

In Mexico, the NAICS is used by INEGI to generate, present, and disseminate statistics on economic activities, seeking to standardize information at the national level and facilitate regional comparability. The NAICS is composed of five levels of aggregation: sector, subsector, branch, sub-branch, and class of activity.

The NAICS provides a framework for analyzing industrial activity at the state level. INEGI’s Monthly Indicator of Industrial Activity by Federal Entity (IMAIEF) uses the NAICS to disaggregate and analyze industrial activity by state. This allows identifying the sectors and branches of activity that are growing or contracting in each federal entity.

The states of Jalisco, Aguascalientes, Guanajuato, Querétaro, San Luis Potosí, and Nuevo León together account for 20% of the population, but practically 38% of the country’s large industry with more than 250 employees per company according to INEGI’s DENUE 2025. That is, it doubles its per capita participation in that sector of the NAICS from 31 to 33.

In Mexico, states such as Guanajuato, Jalisco, and Nuevo León stand out for their strong industrial activity. The manufacturing industry, specifically the sectors of NAICS 311 to 316, which include food, beverages, textiles, leather, hides, and apparel, is concentrated in these entities, although there is also a significant presence in other regions, the highlighted area participates with 37% nationwide.

In Mexico, states such as San Luis Potosí, Jalisco, and Guanajuato are recognized for their strong industrial activity. These states typically have a high concentration of specific manufacturing industries of the NAICS, from codes 321 to 327, referring to manufacturing industries, ranging from the manufacture of wood, paper, and plastic products, to printing and the petrochemical industry. And the highlighted area participates with 40% nationwide.

In Mexico, several states stand out for their strong industrial activity, especially in the manufacturing and extractive sectors, which correspond to NAICS divisions 331 (Basic Metal Industries) to 339 (Other Manufacturing Industries). Among the states with the greatest industrial presence are: Coahuila, Nuevo León, State of Mexico, Puebla, and Guanajuato, among others, the highlighted area participates with 36% nationwide. NAICS code 336110, in the context of North America, refers to the manufacture of automobiles and light trucks.

How Does the Naics Relate to Large Industry by State?

In North America, several states stand out for their automobile production. Within Mexico, states such as Coahuila, Puebla, Guanajuato, San Luis Potosí, Aguascalientes, and State of Mexico are important producers of automobiles and auto parts. In the United States, states such as Michigan, Ohio, Indiana, and Alabama also have a strong presence in the automotive industry. Canada, for its part, has significant automotive production, especially in the province of Ontario.
