The name Nira appears to have gone through periods of popularity and obscurity over the years. Its highest point was in 1933 with an unprecedented 201 births, a figure never reached before or after. However, from 1956 onwards, there seems to be a consistent decline in the number of Nira births each year until it reaches a low of just 5 births per year between 1976 and 1983, a period lasting eight years. It's notable that since 2014, there has been an upward trend with numbers reaching as high as 25 in 2021.
