# SlashData puts the world at ~47M developers — and growth is decelerating

> SlashData's Developer Nation data estimates over 47 million developers globally, but year-over-year growth has slowed to around 10% as the population ages and shifts toward South Asia and Greater China.

SlashData's Developer Nation research estimates the global developer population at over 47 million, with professional developers now the clear majority of that base. The headline for marketers isn't the size — it's the *shape* of the change: growth has decelerated to roughly 10% year over year, the median developer is getting older (fewer 18–24s than a few years ago), and the fastest-growing regions are South Asia and Greater China rather than North America and Western Europe.

For developer marketing, a maturing population changes the math. When the pool was expanding fast, broad awareness plays could ride the growth. A plateau rewards depth: owning a specific segment's trust, ranking for their exact tasks, and being present in their communities. It also raises the value of retention and expansion within your existing developer base over chasing an ever-shrinking pool of net-new signups.

Treat the specific figures as a moving target — SlashData revises them each survey wave — but the direction (bigger, older, more global, slower-growing) has held across recent waves and should shape where you concentrate.

**The take**: A plateauing, aging, geographically shifting developer population means undifferentiated "reach all developers" campaigns get more expensive every quarter. Pick a specific segment — language, role, region, seniority — and go deep enough that those developers consider you the default. Breadth is the losing bet now.
