The fifth edition of the National Family Health Survey (NFHS) provides a valuable insight into changes underway in Indian society. It throws light on traditional parameters, for instance im munisation among children, births in registered hospital facilities, and nutritional levels. While there is a general improvement in these parameters, there were mixed signals in nutrition. Gains in childhood nutrition were minimal as were improvements in obesity levels. The prevalence of anaemia has actually worsened since the last survey in 2015-16. But the survey’s major contribution is its insight into behavioural and sociological churn. When highlights were made public last year, the focus was on India’s declining total fertility rate that had, for the first time in the country’s history, dipped to below the replacement level, or a TFR (Total Fertility Rate) of 2.1. If the trend were to persist, India’s population was on the decline in line with what has been observed in developed countries, and theoretically means improved living standards per capita and greater gender equity. Because this TFR had been achieved across most States, two notable exceptions being most populous Uttar Pradesh and Bihar, it was also evidence that population decline could be achieved without coercive state policies and family planning has struck deep roots. The more detailed findings, made public last week, suggest that this decline is agnostic to religion.
