As per the Census of India 2011, Nagaland recorded a negative population growth rate of -0.58% during the decade 2001-2011. This made it the only state in India to register a decline in population during this period.
The decadal population growth rate for India as a whole was 17.72% during 2001-2011. Most states recorded positive growth, with varying rates. The negative growth in Nagaland was a significant demographic anomaly during this census period.
The reason for the negative growth rate in Nagaland is not definitively established but is speculated to be related to factors like under-enumeration in previous censuses, revisions in enumeration methodology, and potentially socio-economic factors influencing birth and death rates or migration patterns. Other states like Kerala and Tamil Nadu showed relatively low growth rates but were still positive.
