WHAT IT MEASURES
This dataset estimates the share of adults (people 18 and older) who currently report having asthma, using the CDC PLACES project (a Centers for Disease Control and Prevention program that produces local health estimates) built on the Behavioral Risk Factor Surveillance System (a national health survey). It is listed for the City and County and identifies areas by census tract (a neighborhood-sized area the Census Bureau uses). It covers 2021, 2022 and 2023, drawn from the 2023, 2024 and 2025 PLACES releases. Each record also carries a confidence interval (a range in which the true value likely falls) and population figures from the American Community Survey (an ongoing Census Bureau survey). AI

CAVEATS
- These are modeled estimates produced by a methodology, not direct counts of people with asthma, so avoid saying how many people have asthma. AI
- Each estimate has a confidence interval; small differences between tracts or years may fall within that range and not be meaningful. AI
- Each year comes from a different PLACES release and survey year, and the source page's own notes on release timing and survey years are incomplete, so check the Methodology and Measure Definitions pages before citing. AI
- The data lists City and County as places, but the identifier is a census tract, so confirm the geography of any row before describing it. AI

STORY ANGLES
- Which Milwaukee neighborhoods have consistently higher estimated adult asthma rates across 2021, 2022 and 2023, and what local conditions might explain that? AI
- Do the confidence intervals in neighborhoods that look different overlap, and if so, how cautiously should those differences be described? AI
- How do estimated asthma rates in the city compare with the county, and what might that suggest about where health resources are needed? AI
SOURCES
CDC PLACES: PLACES is published by the U.S. Centers for Disease Control and Prevention (CDC) and provides local health data by county, place, census tract, and ZIP Code tabulation area. The page says it uses CDC and U.S. Census data to estimate local health metrics, and it succeeds the earlier 500 Cities project (2016-2019). The page describes PLACES data as estimates produced through a methodology rather than direct counts, and it does not state margins of error or confidence intervals on this page, so reporters should check the Methodology and Measure Definitions pages before citing figures. The latest release noted is August 2024, so the data lags current conditions, and the page does not give the underlying survey years. SOURCE
