Since then, one segment of rap has grown more serious and confrontational.

While driving a delivery truck in college, he had noticed that one segment of laundry business was growing.

It does not matter how large this segment grows.

They worked for an hour, and the segment of metal grew to eight times its original size without any evidence of ending.

That segment has been growing faster than 10 percent a year while the rest of the market is flat.

This segment is growing at an annual rate of about 25 percent in recent years, compared with 3 percent for retailing overall.

The 65-and-over segment in the original suburbs has been growing at nearly double the national rate.

The fastest-growing segment, home services for nutrition, antibiotics and chemotherapy, has been growing 20 to 25 percent a year, the firm says.

Most segments are now growing at less than 5 percent, down sharply from the double-digit growth rates that were routine in the 1980's.

Now a small, but important segment of the market using low-speed and neighborhood electric vehicles is growing.
