What is the most common last name comes from what nationality?

It's impossible to definitively say which last name is the most common *globally*, as different countries and regions have vastly different naming traditions.

However, we can look at the most common last names in specific countries and regions.

Here are some examples:

* Wang is the most common last name in China.

* Smith is the most common last name in the United States, United Kingdom, Canada, and Australia.

* Garcia is the most common last name in Mexico.

* Rodriguez is the most common last name in Puerto Rico and Dominican Republic.

* Müller is the most common last name in Germany.

* Kumar is the most common last name in India.

It's important to note that these are just a few examples. The most common last name in any given country can be influenced by historical, cultural, and linguistic factors.

Instead of trying to find the "most common" globally, it's more interesting to consider:

* What are the origins of common last names in different countries? (e.g., patronymics, occupational names, place names, etc.)

* How do naming patterns evolve over time?

* What are the cultural and social implications of common last names?

These are fascinating topics to explore!
