Greg Clark: Are there ruling classes?

While at UC Davis to give a colloquium earlier this week, I had the pleasure of meeting economic historian Greg Clark in person. Here's a sample of his latest work, which suggests that convergence of social classes has been surprisingly slow: averaged parent-child correlations of variables such as wealth, education and occupation are in the 0.7 -- 0.8 range over the last 200 years, the same as found in India, with its caste system! IIRC, Greg said he got the idea of using rare surnames from Nicholas Wade during an interview :-)

Are there Ruling Classes? Surnames and Social Mobility in England, 1800-2011

Using rare surnames we track the socio-economic status of descendants of a sample of English rich and poor in 1800, until 2011. We measure social status through wealth, education, occupation, and age at death. Our method allows unbiased estimates of mobility rates. Paradoxically, we find two things. Mobility rates are lower than conventionally estimated. There is considerable persistence of status, even after 200 years. But there is convergence with each generation. The 1800 underclass has already attained mediocrity. And the 1800 upper class will eventually dissolve into the mass of society, though perhaps not for another 300 years, or longer.

More discussion, including recent US data, here.
