Software Developers

  • Def of Software Developer
  • 22M developers worldwide - 2017 - [1]
  • 3.8M developers in the USA - 2016 - [2] (source data behind paywall)

Total IT Workers

  • About 10M workers in the USA.

Conclusions

  • 152M total labor force USA, 2016 - [3]
  • GDP of USA is about $19T
  • Salaries are abour 40% of GDP - [4].
  • Thus - if average salary for software developers is $75k - software developers contribute $285B worth of labor. That is about 4% of GDP if adjusted for salaries being 40% of GDP.
  • If we calculate software economy based on total employed population -
  • USA is about 5% of world population.
  • Mean household income USA - $73k [5], and 122M households [6] - for a total USA income of about $8T.
  • If software developers are $285B - then they are 4% of the economy. Both figures match - we get 4% of the economy by both methods.
  • If 22M software developers worldwide - that is $1.7T in earnings - or 5% of the global economy, if adjusted for share of GDP.
