Based on primary sources, baskets of consumption for Buenos Aires are reconstructed for the 1780-1820 period, applying current international methodologies. They build on previous work based on 1835 data. It can be seen that the consumption pattern did not vary substantially in the period and, considering the salary of both urban and rural workers, we are able to establish that standards of living were high and experienced a significant increase after 1835, especially during the 1840s. This placed Buenos Aires among the cities of the Western world with highest welfare ratio levels.
