The introduction to the earlier returns presents the history. Oi census taking in Illinois and gives tables and a map showing the population by counties in 1818 and 1820. This book contains not only the 1820 state census schedules but also notes comparing all discrepancies be tween the names as written in the 1818 territorial, the 1820 state, and the 1820 federal censuses. While in most instances these repre sent merely minor-va'riations in spelling, there are enough marked dis crepancies to indicate that all three sets of returns are necessary to compile a correct list of the pioneers Of each county. Symbols have been used in both volumes to indicate names appearing in the other two censuses. In making this comparison families were not assumed to be identical unless they appeared as residing in approximately the same vicinities. Similarity of names alone was not considered sufh cient unless they were quite distinctive or unless other evidence cor roborated the hypothesis. Names appearing in the federal but not in the state census of 1820 are given in the notes. NO attempt has been made. To compare the number of members ascribed to each family, as the classifications used in the federal census are more detailed than those of the state census, and since it is to be hoped that the 1820 fed; eral census will also be printed before many years.
