Demographic groups include the generations known as Generation Z, Millenials (previously known as Generation Y), Generation X, and baby boomers. Demographic lifestyle parameters include factors such as geography, disposable income, housing, leisure activities, neighborhood, purchasing power, means of transportation, and family status. Demographic information is available from the U.S. Census Bureau website.
Gen Z, also known as iGeneration, includes the children of the youngest baby boomers. This age group is sometimes called the iGeneration because it was born in the age of the Internet, and the children of this group are growing up using electronics and mobile devices.
Millenials or "echo boomers," are also children of the baby boomers' age group. Many people in this demographic lived at home for a longer period of time due to a difficult economic climate.
The Gen X demographic contains 44 million people born between 1965 and the late 1970s; this demographic group is now entering its peak earning and buying years.
The baby boomers are children of parents who lived through World War II; they are now in their 60s and 70s. Boomers spend $400 billion more per year than any other generation. The demographic of people over 65 spends more than $7 billion per year online, much of it on grandchildren.
