Khushi 5 years, 1 month ago

Punjab is known for high agricultural growth but Kerala is known for human resource development. Despite having higher average income than Kerala, Punjab lags behind in health and education facilities. This is because:- ① Income , alone is not an indicator of development. It is material and for development, one needs to include non material aspects like health and education too. ② Kerala was ruled by communist governments post independence . The governments gave high priority to equity and related social groups over time.
