The average density of population is 30 people/km2, but it varies considerably in different parts of the country:
North & South DakotaNebraska
The Pacific Coast
The Cordilleras (Wyoming to Colorado)
However, one should keep in mind the high mobility of the population. It’s closely connected with the rate and level of development of the country. The average American changes the place of living at least 7times during his/her lifetime.
As far as the rate of the urban and rural population is concerned, the US is a highly urbanized society. The percentage of urban settlers comprises 82% of total and the rate of urbanization is 1.2% (census 2010). As for the rural population, it’s only 17,86%.

E Population by Religion
The United States Constitution ensures the right to religious freedom and prevents the development of an official state religion. The lack of official involvement in religion means that no questions about religion are asked in the census and, as a result, limited and sometimes questionable data is available.
The survey below, the American Religious Identification Survey (ARIS) 2008, was a random digit-dialed telephone survey of 54,461 American residential households in the contiguous United States.
It reported that the vast majority of Americans are believers in a single religion - according to a 2007 survey, 78% of respondents identified themselves as Christians. Just over half (51.3%) of all Americans are Protestants, and almost a quarter (23.9%) are Catholic. Other Christian denominations make up 3.3% of the population.
Jews (1.7%), Buddhists (0.7%) and Muslims (0.6%) are the next largest religious groups in the US and 16.1% of Americans declared themselves to have no religion.
NB! Some American religious denominations:
are a group of traditionalist Christian church fellowships. The Amish are known for simple living, plain dress, and reluctance to adopt many conveniences of modern technology.
The history of the Amish church began in 1693 in Switzerland within a group of Swiss Anabaptists led by Jakob Ammann. Those who followed him became known as Amish. In the early 18th century, many Amish immigrated to Pennsylvania for a variety of reasons. Today, the most traditional descendants of the Amish continue to speak Pennsylvania German, also known as "Pennsylvania Dutch". They value rural life, manual labor and humility.
are a Christian group based around the church communities of Anabaptist denominations named after Menno Simons (1496–1561) of Friesland. Through his writings, Simons articulated and formalized the teachings of earlier Swiss founders. The teachings of the Mennonites were founded on their belief in both the mission and ministry of Jesus Christ. Over the years, Mennonites have become known as one of the historic peace churches because of their commitment to pacifism. In the US they appeared in the early 18th century together with Amish and settled in Pennsylvania.
are a religious and cultural group related to Mormonism, the principal branch of the Latter Day Saint movemment. Today Mormons are understood to be members of The Church of Jesus Christ of Latter-day Saints (LDS Church). The center of Mormon cultural influence is in Utah. Mormons self-identify as Christian, though some of their beliefs differ from mainstream Christianity. Mormons believe in the Bible, as well as other books of scripture, such as the Book of Mormon. Central to Mormon faith is the belief that God speaks to his children and answers their prayers. Mormons dedicate large amounts of time and resources to serving in their church. Mormons have a health code that excludes alcoholic beverages, tobacco, coffee, tea, and other addictive substances. They tend to be very family-oriented, and have strong connections across generations and with extended family, reflective of their belief that families can be sealed together beyond death and throughout eternity.
