suicide cases tend to be higher in urban areas, this is triggered by more needs and ambitions for a better life. while in the village live more simple, more simple thinking and needs are also less, so the trigger depression is also small.
There is another reason why the suicide rates are higher in the urban areas. In the cities, the individuals are more likely to be staying away from their relatives and the human interaction may be less. But in the rural areas, there is more interaction with the friends and relatives.
