#####SUMMARY:

We wanted to understand what factors are correlated with Fiber expansion in NYC, and whether there was a change in Verizon's Fiber expansion strategy since 2014. We were also interested in how Fiber expansion related to existing internet access options - whether Fiber is more likely to expand to areas that already have high speed internet coverage, or if we are seeing expansion to areas that are currently underserved.

####METHODS:

We created a multiple regression model using the following data sources:

  • FCC Data on NYC internet access availability (using variables for Fiber Access, and other high speed internet access options)
  • ACS (2014) data on Poverty Rate (using the ACS Lite R Package, census tract level) *NYC Population data (looking at age, and percentage of seniors in the census tract) *Pluto Data on Land Use - Using Variables for Single Family or Multi-Family Units

We used data on tract and block level in our model, using the smallest groupings available for each data source.

Our final model was a fixed-effects model that controlled for county, because we also assumed there could be strong county-level differences in internet access.

##KEY FINDINGS:

Our results suggest a contiunity in Verizon Fiber expansion policy from the baseline time period of 2014 to 2015.

In the baseline model, areas with more single family homes, and other types of high speed internet access predicted fiber availability. This suggests that Verizon was providing Fiber to areas that were already served by high speed internet options, rather than expanding to underserved area. Importantly, Verizon was also less likely to expand Fiber into higher poverty neighborhoods.

We see a continuity in expansion strategy during the next period for 2015. During this period, Verizon continued to expand to well-served neighborhoods, but expanded beyond single family homes to focus on additional land use categories.

These initial results could be expanded by looking at a more expanded time frame (FCC data prior to 2014 is in a different format, which requires more extensive data cleaning).
