Newmarket's demographic composition differs from national averages. The United States is becoming increasingly diverse, with many urban and suburban areas transitioning to Majority-Minority or High Diversity status. In contrast, Newmarket has maintained its Low Diversity classification.

The income growth in Newmarket likely exceeds national averages, suggesting a relatively prosperous local economy. This economic strength, combined with low diversity, may indicate that Newmarket is a relatively affluent, predominantly white suburb or small town that has not experienced the same level of demographic change as other parts of the country.

In conclusion, Newmarket has experienced significant economic growth over the past decade, while its racial composition has remained largely stable, maintaining its status as a Low Diversity, White Majority community. Slight increases in racial diversity, particularly in the multi-racial category, may indicate the beginning of a gradual shift towards increased diversity, occurring at a slower pace than in many other parts of the United States.
