Burt, C. (1966). The genetic estimation of differences in intelligence: A study of monozygotic twins reared together and apart. Br. J. Psych., 57, 147-153. Data is provided in R packages faraway and UsingR.
The data were collected at the 16th Annual Twins Day Festival in Twinsburg, Ohio, in August 1991. 495 adult twins were interviewed. The original study aimed to investigate 'By how much will another year of schooling most likely raise one's income?' Pairs of twins provide a control on confounding factors such as intelligence, family background, etc.

Age in years of twin 1.
AGE squared.
Hourly wage of twin 2.
1 if twin 2 is white, 0 otherwise.
1 if twin 2 is male, 0 otherwise.
Self-reported education (in years) of twin 2.
Hourly wage of twin 1.
1 if twin 1 is white, 0 otherwise.
1 if twin 1 is male, 0 otherwise.
Self-reported education (in years) of twin 1.
the difference (twin 1 minus twin 2) in cross-reported education.
the difference (twin 1 minus twin 2) in tenure, or number of years at current job.
the difference (twin 1 minus twin 2) in marital status, where 1 signifies "married" and 0 signifies "unmarried".
the difference (twin 1 minus twin 2) in union coverage, where 1 signifies "covered" and 0 "uncovered".
There are 183 cases; 147 complete cases. Twin 1's cross-reported education is the number of years of schooling completed by twin 1 as reported by twin 2. For data analysis, the logarithm of the hourly wage is typically used instead of hourly wage.
