The 2011 Census has exposed some noteworthy and perturbing features with regard to regional pattern of sex ratio in Jammu and Kashmir which necessitates some illumination. Since the beginning of this century, the sex ratio in the total population has long been low in Jammu and Kashmir. The provisional data in 2011 Census showed that the overall sex ratio came down to 883 females per 1000 males against 892 females per 1000 males in 2001. Decline in sex ratio in Jammu and Kashmir varies considerably from one region to another. Rapid decline in female-male ratio is a serious problem with severe socio-economic, demographic and cultural implications and if unattended will be disastrous in the very near future. This paper examines the trends, causes and consequences of the decline in sex ratio in the state of Jammu and Kashmir and suggests some possible remedial measures for balancing the male-female population of the state.
