What is the birth frequency of the name 'Neymar' in Brazil per decade?

I've queried the IBGE database for 'NEYMAR'. The name saw a significant rise in the 2000s with 4,685 occurrences, compared to only 436 in the 1990s. Would you like to see the ranking for the 2010s as well?

Show me the top 10 most popular female names in Brazil during the 1980s.

Fetching the 1980s ranking... The top female names were Maria, Ana, and Aline. Maria remains the most frequent with over 1.6 million registrations in that decade alone. Do you want to filter this by a specific state?

Compare the popularity of 'Enzo' and 'Valentina' using IBGE data.

Comparing 'ENZO' and 'VALENTINA'... Both names exploded in popularity in the 2000s. Enzo reached 44,056 registrations while Valentina reached 10,033 in the same period. Would you like to see which states have the highest density for these names?

Yes! Use the `get_name_frequency` tool and separate the names with a pipe symbol (e.g., 'MARIA|ANA'). The agent will return the frequency data for both names across the decades.
