Connecticut School Vaccination Exemption Rates 2024-2025

School-level percentages of vaccination exemptions for the 2024-2025 academic year in Connecticut. The Connecticut Department of Public Health collects this data through an annual immunization survey of pre-kindergarten through 12th-grade schools. Data includes total exemption rates and separate rates for medical and religious exemptions.

Use Cases

• Analyze geographic patterns of exemption rates using the Zipcode, City, and Planning Region columns.
• Compare exemption prevalence between different School Type categories (e.g., public vs. private).
• Model the relationship between total exemption rates (Ex_Tot) and specific exemption types (Ex_Med, Ex_Rel).
• Identify schools with high exemption concentrations by filtering on Ex_Tot and joining with School Name and Address data.

Strengths

• Data is current, covering the 2024-2025 school year.
• Includes separate columns for medical (Ex_Med) and religious (Ex_Rel) exemption rates.
• Provides geographic context with Zipcode, City, and Planning Region fields.

Limitations

• Data for schools with fewer than 30 enrolled students is suppressed, creating gaps.
• Rates are a snapshot from the beginning of the school year and may not reflect mid-year changes.
• Accuracy relies on school-reported data which may contain discrepancies.
