When we consider the conditions enumerated above, it requires no further proof to recognize that a growing number of persons do not regard the wedded state as a desirable goal, but hesitate to enter into it. This explains the phenomenon, that in most civilized countries the marriage rate is stationary or declining. It was a matter of old experience, that an increase in the price of grain had a detrimental effect on both the marriage and birth rates. With the growing industrial development of any country the marriage and birth rates are influenced more and more by the ups and downs of the market. Economic crises and a lowering of the general economic standard have a lasting unfavorable influence. This may be seen from the marriage statistics of various countries. According to the latest census, 12,832,044 marriages were contracted in the United States during the period from 1887 to 1906.
| 1887 | 483,096 |
| 1891 | 562,412 |
| 1892 | 577,870 |
| 1893 | 578,673 |
| 1894 | 566,161 |
| 1902 | 746,733 |
| 1903 | 786,132 |
| 1904 | 781,145 |
| 1905 | 804,787 |
| 1906 | 853,232 |
These figures show that as a result of the crises during 1893 and 1894, the marriage rate declined by 12,512. The same phenomenon recurs in 1904, during which year the marriage rate declined by 4987. The following table shows marriage statistics gathered in France:
| 1873–1877 | 299,000 |
| 1878–1882 | 281,000 |
| 1883–1887 | 284,000 |
| 1888–1892 | 279,000 |
| 1893–1897 | 288,000 |
| 1898–1902 | 296,000 |
| 1903–1907 | 306,000 |
The marriage rate attained its highest figure, 321,238, during the year 1873. From that time on the marriage rate declined only to increase again with times of prosperity. In France the highest marriage rate since 1873 was attained in 1907 when it reached 314,903. To some extent this increase was due to a new law that went into effect on June 21, 1907, by which the legal formalities required in order to become married were simplified. This increase was especially noticeable in the poorer districts. The following table shows the number of marriages contracted for every thousand inhabitants in various European countries:

That the marriage rate rises and sinks with the rise and decline of national prosperity is most strikingly noticeable in Germany. The largest number of marriages (423,900), were contracted in Germany in 1872, the year after the close of the Franco-Prussian war. From 1873 on, the marriage rate declined until in 1879, the year when the crisis was at its worst, it attained its lowest figure (335,133). Then it gradually increased again until 1890, a year of prosperity, to sink once more in 1892 and again to increase with the years of returning prosperity until with the height of prosperity the highest figures were attained (476,491 in 1900, and 471,519 in 1899). The next crisis brought another decline. In 1902 the number of marriages did not exceed 457,208 while in 1906 and 1907 it rose up again to 498,900 and 503,964.
But in general the statistics of most countries point to a decline of the marriage rate. The highest numbers attained during the seventies were attained only in exceptional instances at the close of the nineties. But not only the earnings have a strong influence on the marriage rate, the conditions of property have so likewise. Statistics from the kingdom of Wurtemberg show, that with the increase of large estates the number of married men between 25 and 30 years of age decreases and the number of unmarried men between 40 and 50 years of age increases. Small estates are favorable to the marriage rate, because they enable a greater number of families to maintain a decent though modest livelihood, while large estates are, for obvious reasons, unfavorable to the marriage rate. With the growing industrial development of a country, the number of marriages in urban trades and professions increases. The following statistics from Sweden during the years 1901 to 1904 show the relation of marriage to occupation:
| Agriculture | per | 1000 | 4.78 |
| Industry | “ | “ | 7.17 |
| Commerce | “ | “ | 7.75 |
| Learned professions | “ | “ | 6.33 |
All these figures prove that not moral but economic causes are the determining factors. The number of marriages like the moral status of a social group depend upon its material foundation.
