The decreased number of births in consequence of a bad harvest, and vice versa, appears of course only during the following calendar year. Thus, in 1847, as compared with the average of the years 1844 and 1845, there were fewer children born in England by 4 per 1,000, in Saxony by 7 per 1,000, in Lombardy by 59, in France by 63, in Prussia by 82, in Belgium by 122, in Holland by 159 per 1,000. (Horn, I, 239 ff.) In Germany, the conscription-years corresponding to the scarcity time, 1816-17, gave a minus of 25 per cent. in many places below the average. (Bernouilli, Populationistik, 219.) In the case of marriage, the relative increase or decrease is still more characteristic, so far as our purpose is concerned, than the absolute increase or decrease. Thus in Belgium, for instance, against 1,000 marriages dissolved by death, there were, in 1846, only 971 new ones contracted, and in 1847 only 747; while in 1850 there were 1,500. The falling off in Flanders alone was still greater. Thus, in 1847, there were only 447 marriages contracted for 1,000 dissolved. (Horn, I, 170 ff.) However, Berg, using Sweden as an illustration, rightly calls attention to the fact, that the variations in the number of marriages and births is determined in part by the number of adults, that is, of the number of births 20 and more years before.
