By the Parliamentary return of marriages, births and deaths registered in England and Wales in the year 1881, it appeared that in different districts the percentages of marriages varied considerably. It was greater in the mining, manufacturing and trading districts than in the farming districts, and much higher in London than in the provinces. In the district comprising Hertford, Buckingham, Oxford, Bedford, Cambridge, the rate equalled twelve persons per annum for each thousand of the population. In London it was eighteen persons for each thousand, and in the divisions which comprise Yorkshire and Lancashire the rate was sixteen and seventeen persons to each thousand. As regards births, the proportions stated were somewhat similar. In London there were thirty-five births to one thousand of the population, whilst in the southeastern division there were only thirty-one; but the rate rose again to thirty-five and thirty-six in the great manufacturing districts of the Midlands and the North. Dr. Ogle’s examination of statistics on the subject shows that this state of things has continued, in its main features, up to the present day. “Men marry,” he says, “in greater numbers when trade is brisk. The fluctuations in the marriage-rate follow the fluctuations in the amount of industrial employment.” “The rates vary very greatly in the different registration counties.” “In London the rate is invariably high. Almost all the counties in which the marriage-rate is high are counties in which the population is also high of women engaged in industrial occupations, and therefore presumably in receipt of independent wages, while all the counties in which the marriage-rate is very low are also counties in which but a very small population of the women are industrially occupied.” The general drift of the figures leads to the conclusion that early marriage is most common where there is the largest amount of employment for women. The age at which marriage takes place is examined by Dr. Ogle as “a subject of scarcely less importance than the rate in its bearing upon the growth of the population.” And the point is of special interest in view of the fact that delayed marriage was valued by Malthus as a desirable preventive check. Dr. Ogle finds that the lowest average age at marriage for both bachelors and spinsters, viz., 25·6 and 24·2 respectively, was in 1873, the year in which the marriage-rate was highest; and from that date to the present time the ages have gone up gradually but progressively in harmony with the general decline in the marriage-rate. In 1888 the average age of bachelors at marriage was 26·3 years, and of spinsters was 24·7.
