The demographics of the US population continue to change dramatically, as the absolute number and proportion of older people relative to the remainder of the population increases. Last year, the number of persons older than 65 years was estimated to be 35 million, representing almost 13% of the overall population; by 2030, the older population is expected to double. Along with the general aging of the population, the percentage of persons older than 85 years is also growing rapidly, as is the ethnic and racial diversity within the older population.
