According to the U.S Department of Health and Human Services  the older population—persons 65 years or older—numbered 39.6 million in 2009. They represented 12.9% of the U.S. population, about one in every eight Americans. By 2030, there will be about 72.1 million older persons, more than twice their number in 2000. People 65-plus years old represented 12.4% of the population in the year 2000, but that’s expected to grow to be 19% of the population by 2030. This will mean more demand for elderly care facilities in the coming years. There were more than 36,000 assisted living facilities in the United States in 2009, according to the Assisted Living Federation of America  in 2009. More than 1 million senior citizens are served by these assisted living facilities.
