in the United States in Fifty Years. 53 



comparative effect, because before the last ten years, and since 

 1810, the coloured race had received no accessions from abroad, 

 and had sustained little loss from emigration. 



We have no means of estimating these separate influences, but 

 we learn how great must have been their united effect when we 

 find that if the increase of the free coloured class had been as great 

 in the last ten years as in the ten preceding, their numbers would 

 have been 44,650 more than it was at the late census ; and that if 

 the increase of the slaves had also continued the same, their number 

 would have been 128,000 more than it seems to be at present. A 

 diminution in the rate of decennial increase of the coloured race so 

 considerable as to be equivalent to 172,000 persons, may seem to 

 some yet greater than can be reasonably ascribed to the conjoint 

 effects of emigrations to Texas and to British America, and to the 

 extraordinary mortality which was experienced by the slaves 

 transported to the southwestern States during a part of the last 

 decennial term ; in which case, there seems to be no alternative 

 but to question the accuracy of this part of the census. 



The proportions between the sexes, in the several classes, were 

 as follows : 

 In the white population, the males exceed the females as 100 to 



95.73. 

 In the free coloured population, the females exceed the males as 



107.14 to 100. 

 In the slave population, the males exceed the females as 100 to 



99.55. 



The proportion of white males was greater than it was in 1830, 

 but that of the coloured males was less. The first difference was 

 probably produced by the increased immigration of the whites, and 

 the last by the greater emigration of the coloured race — a greater 

 proportion of those who migrate being commonly males. 



The males and females of each class were thus distributed, ac- 

 cording to age, viz :
