Figure 4. Change in Wage Differences Across CZs at High-, Middle-, and Low-Wage Levels
Source: Authors’ compilation based on 1950–2000 census and 2005–2015 American Community Survey data (Ruggles et al. 2019).
Note: Percentiles represent locations in CZ-specific wage distributions. Lines represent difference in wages at specific percentiles across CZs, specifically those at or above the 95th percentile minus those at or below the 5th percentile. For example, the solid black line in the lower left indicates the difference in wages at the 95th percentile between the most densely populated CZs (such as New York City and Newark, New Jersey) and the least densely populated CZs (such as Lakeview, Oregon, and Jordan, Montana). High pay refers to wages at the 95th percentile, middle pay refers to wages at the 50th percentile, and low pay refers to wages at the 10th percentile.
