A set of historical national accounts for the province of Holland in 1510/14 is estimated, including estimates of the size and composition of the labour force. This evidence shows that the economy of Holland was already very modern at the beginning of the sixteenth century, the result of a transformation of its economic structure between 1350 and 1500, and that structural transformation and per capita growth between 1510/14 and the beginning of the nineteenth century were limited. These results are confirmed by independent evidence about the long term development of real factor prices (rents and wages).
