I’m not all that familiar with the literature on religion, occupation, and occupation, but I can offer a little data. I’m using the General Social Survey, years 2000-2008. You can play around with the data yourself if you google “SDA Archives”. I’m not doing anything fancy with the data, just running some quick numbers. For the sake of this, I’m looking at three groups: Protestant (n=7210), Catholic (n=4257, and Jewish (n=277). There are people who don’t fall into any of those categories, but not enough for anything statistically significant.
First, religion and education in the U.S. Here are the stats:
Among Protestants:
16% have less than a high school diploma;
29% have a high school diploma, but no college;
30% have some college;
14% have a BA/BA;
11% have done some sort of graduate school
For Catholics, the numbers are:
16%
27%
30%
16%
12%
For Jews:
1%
10%
28%
25%
36%
I don’t have a good source of data to answer the question why Jews have higher levels of education, but can offer two hypotheses. First, Jewish religious tradition (as I understand it) emphasizes scholarly learning. Second, Jews are much more likely to live in cities than Protestants or Catholics (GSS data support this: 71% of Jews live in large cities or the suburbs of large cities, compared to 31% of Protestants and 54% of Catholics). People in urban areas have higher levels of education and the job market in urban areas tends to be more white collar/professional.
Next, I looked at religion and occupational prestige. An occupational prestige score assigns each occupation a score from 1-100 based on how prestigious that occupation is. I’m too lazy today to do anything more than look at the distribution, so here it is:
Prestige score % of Prots % of Cath % of Jews
1-24 8% 8% 1%
25-49 58% 58% 46%
50-74 33% 33% 46%
75-100 1% 1% 7%
Basically, Jews are more likely to be in high prestige jobs than Protestants or Catholics. (Note that this does not mean that someone in a high prestige job is more likely to be Jewish than Protestant or Catholic.)
I’d look at the relationship between religion and income, but I can’t find an income variable I’m happy enough with. Hope this helps, though.
