Step-by-step explanation:
The increase in sales of the fastest growing segment can be attributed to several factors. One factor is the increased productivity, which allows businesses to produce and sell more goods.
This leads to a larger variety of goods available to consumers at lower prices, which in turn increases consumer demand.
Another factor is the growth of certain populations, such as minorities and the elderly, which creates a larger market for goods and services targeted towards these segments.
