Introduction:

In Mexico, there is an increase in the number of C-sections, as well as inequity and inequality in the distribution of resources for obstetric care.

Objective:

To identify the states and municipalities in Mexico that concentrate the demand for obstetric care and the C-section rates and their relationship with health resources and women of childbearing age (WCBA).

Method:

Births of the 2008-2017 period were recorded, grouped into five municipal strata, as well as 2017 health resources and WCBA.

Results:

The 2008-2017 national rate of C-sections was 45.3/100 births; 95 and 97 % of births and C-sections were concentrated in the “very high” stratum, where 80 % or more of health resources were used, with overuse standing out. The density of health resources assigned to WCBAs reflected inequity and inequality

Conclusions:

The high concentration of obstetric demand and health resources supply could entail a higher recurrence of C-sections. Policies for C-section reduction should consider proper organization and administration of health resources.
