Portrait of James Clerk Maxwell James Clerk Maxwell,  Popular Science Monthly (1874)

“ When the working members of Section F get hold of a report of the census, or any other document containing the numerical data of Economic and Social Science, they begin by distributing the whole population into groups, according to age, income-tax, education, religious belief, or criminal convictions. The number of individuals is far too great to allow of their tracing the history of each separately, so that, in order to reduce their labor within human limits, they concentrate their attention on a small number of artificial groups. ”

Portrait of Richmond Mayo-Smith Richmond Mayo-Smith,  The Eleventh Census of the United States (1891)

“ Questions l0 to 15 (and 21) are forced upon the census by the peculiar make-up of our population, with its large proportion of persons of foreign birth and of foreign descent. If we neglected to get these statistics and combine them with those of sex, age, conjugal condition, occupation, illiteracy, disease, and death we should miss the greatest opportunity for ethnological and sociological investigation which is offered anywhere in the world, besides depriving ourselves of information absolutely essential to our own welfare. ”

“ The memorialists also urged, for the purpose of more exactly distinguishing the increase of population by birth and immigration, that facts be collected showing the respective numbers of native citizens, citizens of foreign birth, and aliens; and, in order to ascertain more completely the causes which influence life and health, and to furnish a curious and useful document relating to the distribution of society and the conditions and vocations of the people, they urged that facts be collected specifying the number of free male inhabitants, of all ages, engaged in business of various kinds. ”
