Ethiopia
Ethiopia's population has grown from 33.5 million in 1983 to 87.9 million in 2014. The population was only about 9 million in the 19th century. The 2007 Population and Housing Census results show that the population of Ethiopia grew at an average annual rate of 2.6% between 1994 and 2007, down from 2.8% during the period 1983–1994. Currently, the population growth rate is among the top ten countries in the world. The population is forecast to grow to over 210 million by 2060, which would be an increase from 2011 estimates by a factor of about 2.5.
Ethiopian Americans
According to the U.S. Census Bureau, approximately 68,001 people reported Ethiopian ancestry in 2000. Between 2007 and 2011, there were approximately 151,515 Ethiopia-born residents in the United States. According to Aaron Matteo Terrazas, "if the descendants of Ethiopian-born migrants (the second generation and up) are included, the estimates range upwards of 460,000 in the United States (of which approximately 350,000 are in Washington, D. C.; 96,000 in Los Angeles; and 10,000 in New York)." Unofficial estimates suggest that the Washington, D. C., area has an Ethiopian population of 150,000 to 250,000.
