Explanation: Sex-ratio is a critical demographic indicator that reflects the balance between the number of females and males in a population. In the context of Kerala, the sex-ratio varies significantly across different districts due to a variety of socio-economic factors. The sex-ratio is calculated as the number of females per 1000 males, and it is an important measure for understanding gender dynamics and social issues within a region.
Idukki district has the lowest sex-ratio among all districts in Kerala. This can be attributed to several factors:
1. **Migration Patterns**: Idukki is known for its hydropower projects and other industrial activities, which often attract more male workers. This influx of male laborers can skew the sex-ratio towards a lower number of females.
2. **Economic Opportunities**: The district's economy is largely driven by industries that traditionally employ more males, such as construction and manufacturing. This can lead to a higher male population.
3. **Social and Cultural Factors**: Certain social and cultural practices may also influence the sex-ratio, although these are less significant compared to economic factors in Idukki.
In contrast, other districts like Kasargode, Wayanad, and Ernakulam have higher sex-ratios. Kasargode, while having a relatively low sex-ratio, is influenced by similar factors but does not reach the same low levels as Idukki. Wayanad, being a more rural district, has a sex-ratio that is higher than Idukki but still lower than urban districts like Ernakulam. Ernakulam, being a more urbanized district, benefits from a more balanced economic environment that supports a higher sex-ratio.
Understanding the sex-ratio in different districts of Kerala is crucial for policymakers and social scientists to address gender imbalances and promote gender equality. It also helps in planning and implementing policies that can improve the overall demographic balance and social well-being of the region.
