Graphs below provide the latest figure about the demographics of the US, including ethnical groups and the population, based on a census that was carried out and administered by US Census Bureau in 2006.

The table, combined with the bar chart, provides an overview of the demographics of the United States from the early

last

century to the present. It can be seen in the table that the total US

population

is now 300

million

, 1.5 times larger than 40 years ago, 200

million

. Hispanics and Asian

Americans

expanded much faster than other races.

According to

the census, 44.7

million

Americans

are currently Hispanic, more than five times higher than in 1966,

while

the Asian

population

is as large as 14.3

million

, a ten-fold increase over the 1966 level.

By comparison

,

although

white

Americans

are still in the majority, accounting for two-thirds of the current US

population

, the growth rate was lower than the general

population

. Afro-

Americans

, who made up the second largest ethnical group in 1966 with a

population

of 22.3

million

, dropped to number three, behind whites and Hispanics. Other ethnical groups take up the remaining 1.3

million

. In the first half of the 20th century, the US

population

grew at different rates, ranging from

million

to 20

million

a decade, the bar chart suggests. It accelerated since the middle of the

last

, adding at least 20

million

to the

overall

population

every ten years. The 1990s alone experienced a growth of more than 30

million

. To summarise, the US

population

continued to swell since the early

last

century and the greatest increases occurred among Hispanics and Asian

Americans

from 1966 to 2006.
