Let's assume that we want to estimate the number of developers using Python in the USA in 2023.
We have the data from the State of Developer Ecosystem 2023 and can rely on the answers to the following survey questions:
From all the respondents who answered "United States" as their country or region, the share of developers in the USA using Python would be estimated as the weighted share of respondents who answered "Python" as their programming language.
The estimate on the number of developers using Python in the USA in 2023 can then be calculated as follows:
SizeUsaPython = ShareUsaPython х DevPopulationUSA
