Answer:
Migration is the movement of people from one permanent home to another. This movement changes the population of a place. International migration is the movement from one country to another.
The population of any given area can only change through three processes: birth, death and migration. Health departments at the state and local levels keep fairly complete records of births and deaths, but information on gross migration flow—in or out—is practically non-existent. The net effect of migration on population size can be reasonably approximated, however, from census counts and vital statistics. Using data provided by the Indiana State Department of Health, along with 1990 and 2000 census counts, the Indiana Business Research Center estimates that net migration, the difference between inflows and outflows, accounted for 216,000 new state residents in the 1990s—40 percent of Indiana's total population increase for the decade.

This type of study method is referred to as:__________Genomics
Explanation:
Genomics involves the mapping of all genes of an organism – this is called the genome.In addition, genomics is the study of the structure of this genome, how it functions/interactions and evolves over time. The <em>-omics</em> suffix is used to signify ‘ in totality’. This study involves the use of equipment like the high throughput DNA sequencers that sequence DNA. Genomic can be used to diagnose and study genetic diseases like cystic fibrosis & Huntington’s disease.
