Between 1750 and 1850 the population of Sweden doubled. The increase was very unequally distributed among the different social groups of the rural population. The number of peasants grew very little, while the numbers of the landless (crofters, bordars etc.) more than quadrupled. This study examines whether Christer Winberg's thesis of the landless growth can be applied to Björklinge parish in Uppland. Winberg believes that it was mainly children of tenant farmers who became landless. Tax Farmers fell less often and less deeply. To be able to see any particular trends among tenant farmers, I also examine the social mobility of tax farmers. I have therefore chosen three villages with different tax-Axlunda and Gränby is of nobility nature while Hammarby is a village of a fiscal nature. The results show that the two tenant villages, Axlunda and Gränby had two different trends regarding social tenant farmers movement after 1821 onwards. The farmers in Axlunda experienced a strong downward social mobility, while the peasants in Gränby stayed on their farms to a greater extent. In Hammarby it differed significantly between the peasants. The farmers could both move up and down in the social hierarchy.
