I am not sure but I might have one in my thesis published in 2018. Can you be more specific? Are you just looking to classify people into groups with a scale or is there more to it? I believe that when doing my research in the United States I just had to look up national data on what this country considered lower, upper-lower, middle, upper-middle, and upper-class standards in my own country. I got it from our census data does the Philippines

have any national databases like that?
