Will resolve according to data from Pew Research Center, when a report is next published using data from 2024 or 2025.

The latest summary, with historical numbers 1995-2023, is here:

The last four data points are:

2019: 27.0%

2020: 26.50%

2021: 30.00%

2022: 30.40%

If Pew Research Center does not publish a report of this statistic with data from 2024 or 2025 by the end of 2025, then a comparable alternative will be found (with advice from the community). If a comparable alternative cannot be found (for instance, if alternatives do not agree with the historical data from Pew), then this question will resolve N/A.
