Analysis of demographics data
To understand the social impact of the High Line on the Chelsea neighborhood we identified four metrics from the American Community Survey (ACS) data. These metrics were the following:
Median household income
Population density
Highest educational attainment
- Median rent
Like the prior analysis, we performed this analysis on the pre-High Line Chelsea and the post- High Line Chelsea at census tract level. We chose Manhattan without the High Line data as our control group for this analysis. To investigate if the data came from the same distribution we chose to perform a nonparametric K-S test. Further, to analyze of any significant change in the two test sample and the control group, the 2 tailed T-test was used. Among all our metrics, we identified a change statistically significant change in the median household income in the Chelsea neighborhood. As seen in the (Figure 7), there is a 35.67 percent change in the median household income in the Chelsea neighborhood. This change is notable as it is three times the increase in percent change for the rest of Manhattan (10.93 %).
