in spite of the small number of individuals with which it deals:
| Century | Average age | Range | Number of cases |
|---|---|---|---|
| 12 | 16.2 | 8-30 | 5 |
| 13 | 16.6 | 12-29 | 5 |
| 14 | 13.8 | 6-18 | 11 |
| 15 | 17.6 | 13-26 | 20 |
| 16 | 21.7 | 12-50 | 28 |
| 17 | 20.0 | 13-43 | 30 |

Women in coeducational colleges, particularly the great universities of the west, can not be compared without corrections with the women of the eastern separate colleges, because they represent different family and environmental selection. Their record none the less deserves careful study. Miss Shinn4 calculated the marriage rate of college women as follows, assuming graduation at the age of 22:
| Women over | Coeducated | Separate |
|---|---|---|
| 25 | 38.1 | 29.6 |
| 30 | 49.1 | 40.1 |
| 35 | 53.6 | 46.6 |
| 40 | 56.9 | 51.8 |
