A new visualization of Collin County voter registration data highlights significant growth in new voters across several key precincts, with especially notable increases in the eastern and southern parts of the county. The Wylie area stands out as the strongest hotspot, recording the highest concentration of newly registered voters among all precincts. This surge reflects rapid residential growth and continued suburban expansion in that corridor.

McKinney and Princeton also show substantial gains at the precinct level, reinforcing their role as major drivers of the county’s overall voter growth. While individual precincts in these cities vary in scale, McKinney, when viewed as a whole, experienced the largest net increase in new voters countywide, underscoring its position as Collin County’s fastest-growing population center.

In the northwest, Celina emerges as another area of strong momentum. Several precincts there posted solid increases, aligning with the city’s rapid housing development and influx of new residents over the past few years.

A notable political implication of the visualization is that nearly all precincts with the largest increases in new voters now fall within the boundaries of the newly drawn Congressional District 3. This concentration of new registrants could have meaningful impacts on future elections, making CD 3 a district to watch as demographic and political dynamics continue to evolve in Collin County.
