egroes have shifted somewhat from decade to decade,
there have been distinctively Colored sections since 1800.[41]

An idea of this segregation is shown in the fact that in 1900, 80.9
per cent of all the Negro population of Manhattan was contained within
12 out of 35 Assembly Districts and that in 1890 seven wards of
Manhattan contained fully five-sixths of the Negro population of the
Borough. The largest number of Negroes, 13.8 per cent of the total
number, were living, in 1900, in the Nineteenth Assembly District with
numbers approximating this in the Eleventh, which contained 10.4 per
cent, the Twenty-seventh, which had 9.2 per cent, and the
Twenty-third, which had 8.7 per cent of the Negro population. The
Negro population for Manhattan, 36,246, was distributed in 1900 by
assembly districts as is shown in Table IX (p. 49).

These figures give a clear idea of the segregated character of the
Negro population and show something of its present location. There has
been a decided shifting from the part of Manhattan between
Twenty-fifth, Forty-second streets, Sixth and Eighth avenues, and into
Harlem between One Hundred and Thirtieth, One Hundred and Fortieth
streets, Fifth and Eighth avenues during the past five years as
business interests have been taking possession of the zone around the
new Pennsylvania Railway Station, between Thirty-second and
Thirty-third streets. But as the Negroes have moved into blocks in
Harlem, the whites have moved out.
