Percentage of change in population 1911-2011


Observations on Percentage of Change in Population (1911–2011)

Kerala’s population growth rate has gradually declined from 9.16% in 1921–1931 to just 4.91% during 2001–2011, indicating a long-term demographic transition toward population stabilization.

In the early decades, districts like Idukki and Wayanad showed exceptionally high growth (over 70% in 1961 and 1951 respectively) due to migration and settlement in highland areas.

By 2011, Idukki and Pathanamthitta recorded negative growth (-1.79% and -2.97%), reflecting population outmigration and declining birth rates.

Northern districts such as Malappuram and Kasaragod continue to show higher population growth compared to southern districts, highlighting regional demographic variations.

Overall, the data reflects Kerala’s shift from a phase of rapid population growth to near-zero or negative growth, characteristic of a mature and low-fertility population structure.
