In another fascinating example of social statistics, Pew have just released a survey of US beliefs about God. The study included multiple questions about the nature and attributes of God, but my mosaic plot below only looks at the first one. The composition of each column is based on the recent survey, while the width of each column is based on religious composition data from a 2014 study by Pew.
In dark blue, 62% of the US believes in God “as described in the Bible.” A further 30% (in light blue) believes in some other god or higher power (or would not describe their belief in God in more detail). In red, 7% believe in no God at all, and in grey, 1% gave no response.
Columns correspond to denominations: Evangelical Protestant, Mainline Protestant, Historically Black Protestant (HBP), Catholic, Other Christian (OC), Jewish (J), Other Religion (Oth), “Nothing in Particular,” Agnostic (Ag), and Atheist (Ath). Numbers in the “OC” and “Oth” categories were not directly provided by Pew, and were estimated using totals provided (these two columns should therefore be taken with a grain of salt).
Among Christians, 92% of Historically Black Protestants and 91% of Evangelical Protestants believe in God “as described in the Bible,” but only 72% of Mainline Protestants and 69% of Catholics do. What’s more, 1% of Mainline Protestants, 2% of Catholics, and 10% of Jews say that they believe in no God at all (i.e. they adhere to their religion only culturally, and are actually atheists).
On the other hand, 90% of those who describe their religion as “nothing in particular” believe in some kind of God or higher power. So do 67% of agnostics and 18% of atheists (clearly, many who claim to be “nothing in particular” are in fact Christians of some form, and many who claim to be atheists are in fact not).
Part of the explanation for this presumably lies in the fact that religion is in flux for many people in the US. Christians switch between the four main groups, some Christians lose their faith, while other people gain faith in Christianity or in another religion. Religious reality is more complex than a handful of numbers might suggest.
