II. Read the case study given below and answer the questions that follow:
There are three components of population change – births, deaths and migration. Death rate plays an active role in population change. Population growth occurs not only by increasing births rate but also due to decreasing death rate. Crude Death Rate (CDR) is a simple method of measuring mortality of any area. CDR is expressed in terms of number of deaths in a particular year per thousand of population in a particular region. By and large mortality rates are affected by the region’s demographic structure, social advancement and levels of its economic development.
