The population of Mexico has had 4 major periods of growth, they are:
- In the 1860's when Maximillian I invited a large group of German Jews to settle in Mexico.
- 1880's when Ashkenazic Jews fleeing places such as Russia and Romania arrived in Mexico.
- After the fall of the Ottoman Empire when Sephardic Jews began arriving from locations such as Turkey, Morocco, and France.
- Those fleeing Nazi persecution in Europe during World War II.
