In this paper we present an estimation of the GDPs of the provinces in Argentina in 1914 which is the first consistent estimation of this variable for any period before the 1950s. Our results confirm that most of the economic activity in 1914 was located in the province of Buenos Aires; however, some peripheral areas in Patagonia were quite affluent in per capita terms suggesting that resource abundance was an important factor to explain levels of income. The comparison of relative incomes per capita with the available data for 1953 suggests a remarkable stability with no signs of reversal of income but rather persistence or even divergence.
