Chennai vs National Rates

The death rates due to Heart attacks is marginally lesser. It must also be mentioned that the number of deaths due to Diarrhea is significantly lesser compared to national average.  

In any case the the number of the deaths due to cardio vascular diseases, is way higher. Administrations needs to start creating a city where more walking and cycling activities are promoted. Increasing the number of urban spaces to increase physical activity is the need of the hour.
