How many lucas are in the world?

As of my last knowledge update in October 2023, there isn't a specific global count of individuals named Lucas, as names can vary greatly in popularity by region and over time. "Lucas" is a common name in many countries, especially in places like Brazil, the United States, and parts of Europe. For accurate statistics, one would need to consult national census data or name registries, which can provide insights into name popularity in specific areas.
