+ | == Defining Hubs == | ||
+ | '''Summer 2016''' - Last year a master list of 125 "potential" hubs was used. A scorecard was developed which filtered these 125 candidate hubs to determine which of these should be included in the study sample. This method resulted in a sample size of ~ 30. The master list and the final hubs list is titled '''Hubs Data v2_'16'''. It is located here: | ||
+ | Z:\Hubs\2017\hubs_data | ||
+ | |||
+ | '''Summer 2017''' - In order to obtain a more statistically significant sample of hubs, we developed 5 criteria which produce a more relaxed definition of hubs than last year. These include | ||
+ | |||
+ | *Availability of co-working space | ||
+ | *Coding classes or tech events | ||
+ | *Some focus on the tech sector (this is important as our dependent variable is VC funding) | ||
+ | *Presence of an accelerator | ||
+ | *Availability of mentorship for members. | ||
+ | |||
+ | We will review the 125 candidate hubs and select those which satisfy a subset or all of these characteristics. | ||

The Hubs Research Project is a full-length academic paper analyzing the effectiveness of "hubs", a component of the entrepreneurship ecosystem, in the advancement and growth of entrepreneurial success in a metropolitan area. It focuses on cities in the United States as the primary unit of analysis.
This page contains information about data used for this research project, including data sources, location of data on RDP and details on data processing.
Information on initial data work done prior to Summer 2017 can be found at Hubs Summer 2016.
Note on joining: The city-state-year ID from VC data is used as the master ID for joining datasets. Each table (e.g. income, nih, nsf, sbir, compustat) is first joined with the VC data on city-state-year ID and then the resulting tables are all joined together in the final table.

- Zipcode look-up table obtained from https://www.unitedstateszipcodes.org/zip-code-database/. It's available in (E:\McNair\Hubs\summer 2017).
Data by MSA
We have principle cities of MSAs from the census: https://www.census.gov/geographies/reference-files/time-series/demo/metro-micro/delineation-files.html
We might be able to go City -> FIPS place code -> MSA?
Cities and their FIPS codes (which don't perfectly correspond) are available from https://www.census.gov/geo/reference/codes/place.html
The Census claims to provide city to MSA here: https://www.census.gov/geo/maps-data/data/ua_rel_download.html However, there is only CBSA!
This might do it: https://www2.census.gov/geo/pdfs/maps-data/data/rel/explanation_ua_cbsa_rel_10.pdf We can maybe track city to principal city to MSA

Defining Hubs
Summer 2016 - Last year a master list of 125 "potential" hubs was used. A scorecard was developed which filtered these 125 candidate hubs to determine which of these should be included in the study sample. This method resulted in a sample size of ~ 30. The master list and the final hubs list is titled Hubs Data v2_'16. It is located here:
Z:\Hubs\2017\hubs_data
Summer 2017 - In order to obtain a more statistically significant sample of hubs, we developed 5 criteria which produce a more relaxed definition of hubs than last year. These include
- Availability of co-working space
- Coding classes or tech events
- Some focus on the tech sector (this is important as our dependent variable is VC funding)
- Presence of an accelerator
- Availability of mentorship for members.
We will review the 125 candidate hubs and select those which satisfy a subset or all of these characteristics.
