What is meant by market size?

Market size is the total value or the total volume of sales of a product made by all suppliers in a market over a period of time.

Why can a market grow in value while shrinking in volume?

If prices rise faster than the number of units sold falls, total spending increases even though fewer items are being bought.

What is meant by market share?

Market share is the proportion of the total sales in a market that is accounted for by one business or one brand.
