Growth of the Community

New sponsored projects

Four new sponsored projects made NumFOCUS their home:

PyData Network Nearly Tripled in Size

The worldwide PyData community more than doubled, from just over 20,000 members at the beginning of the year to just under 56,000 now! (33 new chapters; 78 chapters total across 34 countries)

Congratulations to all of the PyData chapter organizers on your amazing work growing local communities of data science enthusiasts!

Local communities in New Delhi, India; Warsaw, Poland; and San Luis, Argentina also partnered with NumFOCUS to organize their inaugural PyData Conferences in 2017.
