  1. Businesses in NYC What types of businesses are found in the city? By: Divyanka Sharma

  2. Aim • To understand what types of businesses are found in New York City • What are the concentrations, according to frequency, in each ZCTA? • Can we compare neighborhoods? • What types of business should I open?

  3. Terms and Data Used • ZCTA: Zip Code Tabulation Area. These are conversions of zip codes for easier data analysis. Small differences but mostly the same as zip codes. Only NYC ZCTAs used. • NAICS codes: North American Industry Classification System. These are codes that define the industry that businesses fall under

  4. Data Sources Used • ZCTA: downloaded from census bureau • NAICS codes: dataset bought from Dun and Bradstreet, a data provider. This contains the names of all businesses, their NAICS codes, Zip codes, and other top level information, for the entire United States. This was bought by my company.

  5. Cleaning the data • First step is to extract only NYC data from the US file • Convert zip codes to ZCTA’s for easy comparison. Also useful if want to run more tests using other census info later. • Attach descriptions of NAICS code id #’s to the dataset for readability of data

  6. What do we find? • The top 10 most common businesses, by frequency of physical outlets, are the following:

  7. Example plots of businesses in certain ZCTAs

  8. Queens

  9. Manhattan

  10. Brooklyn

  11. Queens

  12. The Bronx

  13. Problems with the data • The data is from 2012, so there could be some changes • The NAICS codes themselves are not very clear. Example: “all other businesses” category • This is self reported data, so there can be biases

  14. Future Potential • Can layer other information on top of this to study more trends • Can analyze what businesses an entrepreneur should look into starting in certain ZCTAs • If time series data available, plot the change in frequency of businesses
