Greg, I will be happy to let you know. I haven't received any information yet, on Population data for the years 1825-1875. All I have at hand is an old book: Historical Atlas of the United States, by Clifford Lord and Elizabeth H. Lord. 1944. This book has a lot of data on entire areas of the country, and of whole Territories, but I haven't yet found any statistics by state or by town. A search of the net hasn't yet provided anything for those years. There may not be such information available, but if there is, maybe someone on the list will know where we can find it. I will certainly post to the list, anything I find. Arlene
