This chart and map track recent movements in single-family home sales in Harford County by ZIP code. The chart lists sales volume and median price for December 1991, the most recent month for which data is available, and for all of 1991, and compares those figures with 1990 statistics.

In future weeks, charts and maps will appear for Anne Arundel County; Baltimore and Baltimore County, and Howard and Carroll counties.

At the end of March, a metro-wide roundup of 1991 sales trends will appear.

These figures show general residential real estate price trends, and should not be misconstrued to show the relative increase or decrease in value of any particular property. At any time, there may be more sales in certain market niches -- starter homes, for example -- and this may distort the median price.
