The data will be collected from a sample of the residents living in a city. Simple random sampling method will be used due to its ease and time requirement. Although easy to conduct, this research method has a few drawbacks because the sample might not relate to those people who do not like in cities. The behavior of people also varies from region to region. All these issues have been kept aside in this research.

It is primarily used to study diseases that are not common or new. They are observational in nature and therefore, do not provide an accurate result. Apart from collecting primary data, secondary data may also be analyzed to ...
