This page records every time the data behind our calculators changes. Scaling is recalculated every year, so the tables are replaced after each results season. The current data year is 2025 for every state.

What happens next
When the 2026 scaling reports are released after results in December 2026, each state's table will be replaced and listed here with the date it changed. How the numbers are used is explained on the methodology page.
