Chicago Asthma Hospitalizations by ZIP Code, 2000-2011

Data.cityofchicago.org provides historical public health statistics on asthma hospital discharges for Chicago from 2000 to 2011. The dataset includes annual counts, crude rates, and age-adjusted rates per 10,000 residents aged 5-64, with 95% confidence intervals, aggregated by U.S. Postal Service ZIP code. This historical dataset was last updated on the platform in February 2022.

Use Cases

• Analyzing temporal trends in asthma burden using Hospitalizations 2003, Hospitalizations 2006, and Hospitalizations 2007 columns.
• Mapping geographic disparities in health outcomes by comparing Crude Rate 2005 and Crude Rate 2008 across ZIP code aggregates.
• Assessing statistical reliability of rate estimates by examining confidence intervals like Crude Rate 2004 Upper CI and Adjusted Rate 2006 Lower CI.
• Studying age-adjusted hospitalization patterns for the 5-64 population using columns such as Adjusted Rate 2001 (Ages 5-64 only) and Adjusted Rate 2009 Lower CI.

Strengths

• Provides 12 years of longitudinal data from 2000 to 2011.
• Includes multiple statistical measures: raw counts, crude rates, and age-adjusted rates with confidence intervals for robustness.
• Data is spatially disaggregated to the ZIP code or ZIP code aggregate level for local analysis.

Limitations

• Data is historical only, with no corresponding datasets for years after 2011 noted in the description.
• Row count and dataset size are unknown, which may limit suitability assessment for large-scale modeling.
• Description metadata is limited; actual data quality and completeness require manual inspection after download.
