#StataViz

Once in a while I do presentations on #StataViz.

🌍 Today we explore demographic change for Uni Rosario in Bogota, Colombia.

🌏 Last month, we explored the relationship of nightlights and PM2.5 for Azim Premji Uni in India.

This is an exciting break from the regular research grind!

Relaunching my #StataViz #Portfolio website with a new look.

Still a work-in-progress but check it out!
