Real-Time County Demographics

The `get_demographics_by_county` tool pulls racial and ethnic breakdowns for every county in a given state. You can show users exactly which groups live where, making market segmentation instant. This data is perfect for visualizing diversity maps. It handles states across the board, letting you pull White, Black, Asian, Hispanic, and foreign-born counts for any place.

State Diversity Analysis

Need a high-level view? The `get_demographics_by_state` tool delivers racial and ethnic demographics across entire states. Your app gets White, Black, Asian, Hispanic, and foreign-born counts immediately. It’s ideal for policy research where you need to compare state-to-state diversity metrics side-by-side without complex backend joins.

City Population Counts

The `get_population_by_city` tool grabs the population count for incorporated cities and Census Designated Places within a state. This lets your frontend display localized stats right away. It doesn't just give a number; it provides granular location data necessary when you need to target specific towns or communities in your application.
