- GeoSeries.pct_change(periods: int = 1) Series#
Fractional change between the current and a prior element.
Computes the fractional change from the immediately previous row by default. This is useful in comparing the fraction of change in a time series of elements.

- Parameters:
periods (int, default 1) – Periods to shift for forming percent change.
- Returns:
The same type as the calling object.
