Which southern Dallas suburbs are "fast-growing?"

I'm wondering which suburbs in the southern part of Dallas County have grown significantly in the past decade or so. Any insight, especially from area residents, would be greatly appreciated.

Mel71082,
I lived in the southern suburbs for 20+ years. I'll take a shot at answering your question.

Most of the cities in southern Dallas County have grown in population over the last decade, some more than others.

Population Comparison (2000 Census/2009 Estimate)
DeSoto (37,646 / 48,700)+11,054
Cedar Hill (32,093 / 45,600)+13,507
Duncanville (36,081 / 38,850)+2,769
Lancaster (25,894 / 36,200)+10,306
Glenn Heights (7,224 / 12,100)+4,876
Seagoville (10,823 / 13,850)+3,027
Wilmer (3,393 / 3,300)-93
Hutchins (2,805 / 3,050)+245

Population Growth Rates, 2000-09
67.5% Glenn Heights
42.1% Cedar Hill
39.8% Lancaster
29.4% DeSoto
28.0% Seagoville
8.7% Hutchins
7.7% Duncanville
-2.7% Wilmer

Among the larger cities, Cedar Hill and Lancaster have grown the most. Glenn Heights, which is situated on the Dallas/Ellis County border is the fastest growing among smaller communities. These communities are growing much faster rate than the Dallas-Fort Worth Metroplex as a whole.

I hope you find this information helpful.

Thanks Chris N! Your information was very helpful.
