In 2030, the population of the USA will reach 356 million, an increase of 13.4% from 2012. The USA’s population is ageing and this is compounded by falling birth rates. Meanwhile the average age at childbirth is also climbing. Migration is an important driver of population growth and will grow in importance during the forecast period. This is despite a slight slow down in population growth, due to a fall in natural change. New York is the largest city and this will remain so in 2030.
