Using just these variables,

Population growth = Population*(Birth Rate - Death Rate).

However, a couple of real-life refinements:

1. Although the number of births and deaths depends on the population, it is related to the age-structure of the population. A very old population, for example, will not have many births but many deaths whereas a young population will have more births and fewer deaths. So, the population should be stratified according its age structure.

2. Net migration also needs to be taken into account.
