Instituto Mexicano Del Seguro Social
In short
The Mexican Social Security Institute is a government organisation that manages public health, pensions, and social security for workers in Mexico.
In plain words
It is a large system that looks after people's health and money for when they retire. It works alongside the Mexican healthcare system to provide medical care and financial support.
A simple example
A factory worker pays into the system through their wages so they can visit a doctor for free and receive a pension when they stop working.
Why it matters
It provides a vital safety net for millions of Mexican citizens. Without it, many workers would have no access to affordable medical treatment or stable income during old age.
Easy to mix up
Do not confuse it with the Secretariat of Health, which is the broader government department that oversees it.
