Apparatus
Sources and method
The figures for San Salvador de Jujuy are the UN's own, at five-year steps: an estimate for each of 1975 to 2025, then projection to 2050. Projected years are drawn hatched, and the UN publishes no range of uncertainty for a city. What a city means here, how the UN measures one, and why that number can differ from the one San Salvador de Jujuy publishes about itself: how the figures here are put together.
