What LinkedIn Tells Us About Developer Population in the World
There are tons of articles about the number of developers in the world. But most of them either lack good methodology or simply borrow statistics from other resources.
Here's what I did differently. I counted a real number of developers according to the preferred language in European countries and the US based on LinkedIn data.
As a result, I found out that:
- The US has the biggest number of developers specializing in Java — 63K, JS — 12K, Python — 10K, and Ruby on Rails — 3K.
- The UK follows the US and Ukraine closely by the majority of technologies. There are 14K Java developers, 5K JS and PHP engineers, and 2K Python software programmers in the UK.
- The numbers of developers in the Netherlands and Germany coincide in many technologies. For example, there are around 6K Java and 3K JS developers in both countries.
Apart from researching the numbers of developers in the US, the UK, Germany, the Netherlands, and Ukraine, I've also decided to dig into the distribution of developers by seniority levels.
PHP developers: number and distribution by seniority
Ukraine has 9K PHP programmers, the US follows with 7K, the UK goes next with nearly 5K PHP developers. Germany and the Netherlands close the list with 2K+ and almost 3K PHP developers correspondingly.
Java developers: number and distribution by seniority
The US has the biggest number of Java developers — there are 63K professionals. The UK — 14K, Ukraine — 8K Java programmers, while Germany and the Netherlands go behind with 6K Java engineers each.
Python developers: number and distribution by seniority
The US has more than 10K Python developers, Ukraine follows with 3K, the UK has 2K+, while Germany and the Netherlands are behind with around 1K Python developers in each country.
There are almost 12K JS developers in the US, 8K in Ukraine, 5K in the UK, 3K in Germany and the Netherlands.
Ruby on Rails developers: number and distribution by seniority
There are 3K Ruby on Rails developers in the US, 1K in Ukraine, 700 in the UK, 600+ in Germany, around 300 in the Netherlands.
The research helped me to make three valuable conclusions:
- The larger population doesn't always mean a bigger number of developers — Ukraine has more PHP developers than the US.
- Countries with divergent population sizes can have similar numbers of programmers — by the majority of technologies Germany (84M population) and the Netherlands (17M population) have similar numbers of programmers.
- Ukraine has an even distribution of developers by the seniority levels if compared to other countries.
