ioo Negro Migration 



pare these local increases with the increase in the total Negro 

 population of the United States during the decade 1900-1910. 

 The rate of increase for the whole country, 11.2 per cent, 

 may be taken as a rather accurate measure of the excess of 

 Negro births over deaths for the 10 years, since the country 

 as a whole was neither gaining nor losing perceptibly by in- 

 ternational Negro migration. In order that this determin- 

 ation might not be too arbitrary, however, a range from 7j^ 

 to 15 per cent may be taken as indicative of excess of births 

 over deaths. Any area whose increase in Negro population 

 for the decade falls between these limits may be considered a 

 stationary area as far as perceptible migration is concerned. 



Districts whose Negro population increased at a rate 

 slower than 7j4 per cent may be considered as losing by 

 migration and those increasing at a rate faster than 15 per 

 cent considered as gaining by migration. Districts increas- 

 ing at a rate of over 20 per cent can be said to be gaining 

 rapidly by migration. 



Map II indicates these rates of increase for the rural dis- 

 tricts of Georgia. 6 Of the 144 counties shown on the map 

 the 16 mountain counties and 24 counties containing towns 

 of over 2,500 are left unshaded. The remaining 104 rural 

 counties are shaded to indicate their increase in Negroes. 

 The shading shows that the 7 stationary counties are well 

 scattered. Of the 97 other counties, 37 were losing, 24 

 gaining slowly and 36 gaining rapidly. A glance at the map 

 shows that the decreasing area corresponds closely to the 



6 Based on percentages of increase shown in U. S. Census 

 "Negro Population in the United Slates, 1790-1915." Table II. 

 Counties grouped at the end of this table under "Notes on 

 Changes in Boundaries" are grouped in the Map and the in- 

 crease figured for the whole area because changes in county 

 lines make census figures deceptive as to increase or decrease 

 of individual counties in the area. In case a city was located 

 in such an area its population was deducted. Inasmuch as there 

 was an adjustment between the Urban county of Clarke and the 

 rural county of Oglethorpe, the latter was left unshaded.
