The economic performance of Argentina in the long run is quite usually divided in two periods: in the first one (1870-1914) we observe openness, low levels of public intervention and rapid growth in relative terms, while in the second (1914-1970) we observe relative economic slowdown together with inward looking policies and higher levels of public intervention. While there are many reconstructions of the evolution of main macroeconomic variables at a national aggregate level since the second half of the nineteenth century and many descriptions of the sectorial dimensions of this process, the available information about its provincial or regional dimensions is very scarce. In this paper we present an estimation of the GDPs of the twenty four provinces in Argentina in 1914 which is the first consistent and comparable estimation of this variable for any period before the 1950s. Our results confirm the standard view that most of the economic activity at the end of the period of the first globalization is located in the central area of the country and, in particular, in the province and city of Buenos Aires which seems to have been a quite important pole of economic activity; however, we also show that some peripheral areas in Patagonia, with very low population density, are quite affluent in per capita terms suggesting that resource abundance was an important factor to explain levels of income per capita. The comparison of the relative incomes per capita of the provinces in 1914 with the available data for 1953 suggest a remarkable stability and indicates that in this period there were no signs of reversal of income but rather persistence or even divergence
