Covered California Health Plan Enrollees by Rating Region

Data from 2026 details eligible individuals who selected, enrolled, and paid for a Covered California Qualified Health Plan, segmented by the state's 19 rating regions. The dataset originates from the California Healthcare Eligibility, Enrollment and Retention System (CalHEERS) and fulfills public reporting requirements.

Use Cases

• Analyze enrollment counts across the 19 rating regions to identify geographic disparities in health insurance uptake.
• Track enrollment trends by reporting period to assess the impact of policy changes or marketing campaigns.
• Model regional pricing variations for Qualified Health Plans using rating region as a key segmentation variable.

Strengths

• Data is sourced from the authoritative CalHEERS system, ensuring official reporting accuracy.
• Provides granular segmentation across California's 19 distinct health insurance rating regions.
• Includes a specific legal mandate reference (California Welfare and Institutions Code 14102.5) for transparency.

Limitations

• The dataset lacks detailed column definitions, making precise analysis of variables like 'eligible individuals' or 'reporting period' difficult.
• Without row counts or sample data, the scale and completeness of the dataset cannot be verified.
