BACKGROUND OF THE STUDY: Population in India was not growing rapidly till the early twenties of the last century. It was nearly static, with a relatively safe and acceptable rate of annual growth, since both birth and death rates were relatively high .With advances in technology and expansion of health services death rate started declining in the following decades. Meanwhile the birth rate continued to persist at the same level .This caused a severe demographic gap between the birth and death rate, and resulted in growth of population at an alarming rate. OBJECTIVE: To assess the knowledge and perceived barrier regarding IUCD. METHOD AND MATERIAL: A quantitative research approach with non experimental comparative descriptive study was adopted in this study. The non-probabality, purposive sampling technique was used to select the subject for the study. Data collected from 100 subjects were analyzed by descriptive and inferential statistics. The overall findings on the IUCD knowledge and perceived barrier scores of women residing in urban and rural area revealed that 70% women from the urban areas and 88% from the rural area had moderate knowledge regarding IUCD and 68% women from the urban areas and 92 % women from the rural area had perceived barrier about IUCD usage .Comparison of knowledge and perceived barriers regarding IUCD among urban and rural women shows that there is a significant difference in level of knowledge and perceived barrier. CONCLUSION: The study showed that only 30 % women from the urban area had adequate level knowledge regarding IUCD and none from the rural area had adequate level of knowledge about IUCD. Perceived personnel barrier also was considerably more in comparison to service barrier. The overall findings of the study depicted that the there is a need for educating people regarding IUCD.
