The demographics of countries have dramatically changed in recent years. It is mainly reflected in the population composition and indicators such as birth/death rate and life expectancy. The changing demographics have a great effect and impact the society in different ways that alter how a business should adjust their target market. The following indicators allow us to quantify these demographic shifts.

The first indicators focus on the United States population. Statistics that help to identify the composition of the population are very important in visualizing how society is changing in terms of a few metrics. These important metrics include number of persons in each age demographic over the past 50+ years and what direction change is occurring. The next is immigration patterns in various possible scenarios that exemplify how population growth could be dependent on immigration. Lastly, within this idea of immigration bolstering the growing U.S. population is the number of documented permanent residents in the United States.

The next indicator is life conditions, which allow researchers and businesses to understand the lifespan and conditions of their market. The first metric under this indicator is the United States birth rate, which helps visualize the ease of childbirth and the increasing safety over the past years. Lastly, the average life expectancy is of utmost importance to understand the average human lifespan and adapt business plans around longer, healthier lives.

Trend

The aging population is rapidly increasing due to declining fertility rates world wide, which in turn reduces the number of available workers. Advances in medical technologies, and in particular the spectacular decline in the cost and time required to map the human genome holds the promise of further dramatic increases in life expectancy, and in particular, the prospect of staying healthier and more active in later life.
