# Appendix C: The history of the political typology

The Pew Research Center political typology aims to sort Americans into groups based on their political values and beliefs. The current study – Pew Research Center’s ninth political typology study since [the first one in 1987](https://www.pewresearch.org/politics/1987/09/30/the-people-the-press-politics/) – is based on a survey conducted among 10,357 adults on Nov. 17-30, 2025. Previous versions of the political typology were conducted in [1994](https://www.pewresearch.org/politics/1994/09/21/the-people-the-press-politics-2/), [1999](https://www.pewresearch.org/politics/1999/11/11/retro-politics/), [2004](https://www.pewresearch.org/politics/2005/05/10/beyond-red-vs-blue/) (published in 2005), [2011](https://www.pewresearch.org/politics/2011/05/04/beyond-red-vs-blue-the-political-typology/), [2014](https://www.pewresearch.org/politics/2014/06/26/the-political-typology-beyond-red-vs-blue/), [2017](https://www.pewresearch.org/politics/2017/10/24/political-typology-reveals-deep-fissures-on-the-right-and-left/) and [2021](https://www.pewresearch.org/politics/2021/11/09/beyond-red-vs-blue-the-political-typology/).

The first political typology in 1987 was conducted using face-to-face interviews. Political typologies from 1994-2017 were conducted by telephone. Beginning with the 2021 typology, interviews have been conducted using the Center’s primarily online [American Trends Panel](https://www.pewresearch.org/the-american-trends-panel/).
