Data Updates

MaineTracking Network is ever-evolving. This page highlights the data portal topics we updated from 2023 to present.

Annual update refers to a scheduled update that may include new years of data, new measures (e.g., hospitalizations, emergency department visits), new display types (e.g., near real-time, trend-charts), or even new data portal topics.

Erratum refers to an identified data discrepancy. For an explanation of what took place and if changes in procedures were needed and added, please refer to the Details column.

Please email us at metracking@maine.gov or fill out the Contact Us form with any questions or comments.
