Population declines were also common, with losses occurring in nine states and Puerto Rico. The nine states that lost population last year were New York (down 48,510), Illinois (45,116), West Virginia (11,216), Louisiana (10,840), Hawaii (3,712), Mississippi (3,133), Alaska (2,348), Connecticut (1,215) and Wyoming (1,197).

“Many states have seen fewer births and more deaths in recent years,” said Sandra Johnson, a demographer/statistician in the Population Division of the Census Bureau. “If those states are not gaining from either domestic or international migration they will experience either low population growth or outright decline.”

Nationally, natural increase (the excess of births over deaths) was 1.04 million last year, reflecting 3,855,500 births and 2,814,013 deaths. With fewer births in recent years and the number of deaths increasing, natural increase has declined steadily over the past decade. In 2008, natural increase was nearly 1.8 million (based on National Center for Health Statistics data).

Also released today were national- and state-level estimates of the components of population change, which include tables on births, deaths and migration.
