Sales for the market rose from $7.9 billion to $10 billion from 1998-2003, an increase of 27% in current prices and 12% in constant prices. These gains were made in spite of losses in constant dollars to the median income for households in the U.S. Median income is relevant to the market because households with annual income of $50K or more are more likely to participate in the market. If the economic climate shifts to one in which the majority of American households make gains rather than a minority, the market will show more demonstrable gains in ensuing years.
