Table I. gives the number of illegitimate births per 1000 births in various countries of the world for quinquennial periods. It is to be noted that still-born births are excluded, as in the United Kingdom (contrary to the practice prevailing in most European countries) registration of such births is not compulsory. The United States is omitted, as there is no national system of registration of births.
This method of measuring illegitimacy by ascertaining the proportion of illegitimate births in every thousand births is a fairly accurate one, but there is another valuable one which is often applied, that of comparing the number of illegitimate births with each thousand unmarried females at the child-bearing age the “corrected” rate as opposed to the “crude,” as it is usually termed. This is given for certain countries in Table II.

The generally accepted idea that the inhabitants of the warmer countries of the south of Europe are more ardent in temperament has at least no support as shown in the figures in Table I., where we find a higher rate of illegitimacy in Sweden and Denmark than in Spain or Italy. Religion, however, must be taken into account as having a strong influence in preventing unchastity, though it cannot be concluded that any particular creed is more powerful in this direction than another; for example, the figures for Austria and Ireland are very different. It cannot be said, either, that figures bear out the statement that where there is a high rate of illegitimacy there is little prostitution. It is more probable that in a country where the standard of living is low, and early marriages are the rule, the illegitimate birth-rate will be low. As regards England and Wales, the illegitimate birth-rate has been steadily declining for many years, not only in actual numbers, but also in proportion to the population.

| Year. | Illegitimate Births. | Proportion to 1000 of population. | Illegitimate Births in 1000 Births. |
| 1860 | 43,693 | 2.2 | 64 |
| 1865 | 46,585 | 2.2 | 62 |
| 1870 | 44,737 | 2.0 | 56 |

The corrected rate bears out the result shown in Table III as follows:
