Demographic engineering is deliberate effort to shift the ethnic balance of an area, especially when undertaken to create ethnically homogeneous populations. Demographic engineering ranges from falsification of census results, redrawing borders, differential natalism to change birth rates of certain population groups, targeting disfavored groups with voluntary or coerced emigration, and population transfer and resettlement with members of the favored group. At an extreme, demographic engineering is undertaken through genocide.

The Armenian genocide was the systematic destruction of the Armenian people and identity in the Ottoman Empire during World War I. Spearheaded by the ruling Committee of Union and Progress (CUP), it was implemented primarily through the mass murder of around one million Armenians during death marches to the Syrian Desert and the forced Islamization of others, primarily women and children.
