Indonesia: Secondary education, teachers

Key figures

Over five years it is up 5.09% from 1.29 million in 2020 (1% a year on average, compounded). Since 1970 it is up 620.78% from 187,776 in 1970 (3.66% a year on average, compounded). The World Bank has no value for 8 of the years in between; the chart leaves those gaps open rather than joining across them.

What the numbers say

In 2025, Indonesia's secondary education, teachers rose 0.7% on 2024 (from 1.34 million to 1.35 million).

Across the 30 yearly changes before that (1993 to 2024), the average change was +1.5% and a typical year strayed about 7.2% from that (the standard deviation). This year's change was 0.1 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 16.4% in 1983 and the biggest yearly fall was 23.9% in 2019. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2016 to 2025 the straight-line trend is downward, about 35,770 a year. A straight line explains 47% of the movement over 10 observed years.
