The clan has now reached its ninth generation and its present status has been exhaustively studied by A. H. Estabrook (The Jukes in 1915: Carnegie Institution of Washington, 1916). He enumerates 2,820 individuals, of whom half are still living. In the early 80's they left their original home and are now scattered all over the country. The change in environment has enabled some of them to rise to a higher level, but on the whole, says C. B. Davenport in a preface to Estabrook's book, they "still show the same feeble-mindedness, indolence, licentiousness and dishonesty, even when not handicapped by the associations of their bad family name and despite the fact of being surrounded by better social conditions." Estabrook says the clan might have been exterminated by preventing the reproduction of its members, and that the nation would thereby have saved about $2,500,000. It is interesting to note that "out of approximately 600 living feeble-minded and epileptic Jukes, there are only three now in custodial care."
