Important Notice: The last update to the hubs data was done manually by Ed and is in E:\projects\MeasuringHGHTEcosystems\HubsData-RevisedSimplified.xlsx

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.

Data by zip code

Population data, 2000-2016 - US Census Bureau (E:\McNair\Hubs\summer 2017)

https://www2.census.gov/programs-surveys/popest/datasets/

Income data, 1998-2014 - The Internal Revenue Service (E:\McNair\Hubs\summer 2017)

https://www.irs.gov/uac/about-irs

DCI index, to assess the economic well-being of communities

http://eig.org/dci/interactive-maps/u-s-zip-codes

R&D Expenses, 1980-2016 - Wharton Research Data Services (E:\McNair\Hubs\summer 2017)
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.

-===Primary Data Set===
-The Hubs data set, from SDC Platinum, has been constructed in the server:

+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.
-The data set includes all United States Venture Capital transactions (moneytree) from the twenty-five year period of 1990 through 2015.
+This page contains information about data used for this research project, including data sources, location of data on RDP and details on data processing.
-Data has been aggregated at the portfolio company, fund, and round level. It will be analyzed at the combined MSA level. We will be looking at in terms of number of companies funded in  number of funds active, and flow of investment in a given MSA.
-The data set has now been uploaded to the database server, named Hubs.
-There are 4 tables:
-*Rounds: Rounddate, coname, state, roundno, stage1, etc.
-*CombinedRounds: Coname, rounddate, discamount, fundname
-*Companies: LastInv, FirstInv, coname, MSA, MSACode, Address, state, datefounded, totalknownfunding, industry(major)

-===Hub Candidates Data Set===
-The Hubs candidate data set is a list of potential hubs found in MSAs throughout the country. Researchers are currently pulling qualitative and quantitative information from the candidate's websites, in an attempt to categorize what can be identified as a hub. This is a difficult data set to pull, as there is little to no quantitative information available for this category of institution, and is dependent on accessibility of information to the public on the internet.
-Characteristics/Variables
-*Year Founded
-*Square footage
-*LinkedIN self-identifiers (what the organization classifies itself on its LinkedIN profile)
-*Activeness on Twitter (binomial)
-*Member Directory available online (binomial)
-*Number of conference rooms
-*Price ($/month) for Flex desk
-*Offers Reserved desk (binomial)
-*Offers office space for rent (binomial)
-*Offers community membership-- not for coworking but for community events, etc. (binomial)
-*Number of events offered per month (estimate)
-*Offers code academy
-*Mission Statement/Vision (for qualitative or key-word analysis)
-These characteristics/variables will be used to determine whether a candidate is or is not likely to be a Hub.
-As of March 10th 2016, the list contains 125 Hub candidates.
-'''Where to find''': The Hubs data set can be found in the Ecosystem>>Hubs>>dataset folder. It is not currently in the database due to a UTF8 issue
-===Supplementary Data Sets===
-'''Patent data''': to be pulled from USPTO or SDC Platinum.
-'''Number of STEM Graduate Students''' (NSF) and '''University R&D Spending''' (NSF):
-*University R&D Data found under file "NSF DATA_2004 to 2011.xlsx" in datasets folder (Ecosystem>>Hubs>>Datasets)
-*R&D spending found at the university level for 2014 ("Stem Grad Students.xlsx) or at state level ("Science and Engineering Grad Students by State and Year 2000-2011.csv")
-** not uploaded to server or matched yet to CMSA code, because of this discrepancy.
-**"Stem Grad Students.xlsx" contains categorized university by MSA, can be used for all university-based projects
-'''Per Capita Income''' and '''Employment Data''' (US Census Bureau):
-*"Per Capita Personal Income by MSA 2000-2012.xlsx" in datasets folder (Ecosystem>>Hubs>>Datasets>>Data from Yael)

-*includes birth, death, net(birth-death) and rate(death rate) for years 1990-2013 for every msa
-*includes code for CMSA but is not aggregated by CMSA
-** i.e. BDS statistics are still separate for all the smaller MSAs in New York's CMSA (code=1)
-===Resources===
-* Yael Hochberg and Fehder (2015), located in dropbox
-** Use this paper as a guideline on how to conduct the analysis
-*US Census Bureau data on employment by MSA: http://factfinder.census.gov/faces/tableservices/jsf/pages/productview.xhtml?pid=ACS_14_5YR_B23027&prodType=table
-*USPTO utility patents by MSA: http://www.uspto.gov/web/offices/ac/ido/oeip/taf/cls_cbsa/allcbsa_gd.htm
-*MSA level trends: http://www.metrotrends.org/data.cf
-===The Target Dataset===
-We will need to process the following variables:
-*SuperMSA - combine SanFran and SanJose, New York and Newark?, NC Research triangle, others?
-*CSV mapping msas to cmsas is in the folder (and a table in the dbase)
-Example dataset:
- MSA      Year       SeedVCInv      SeedEarlyVCInv      LaterVCInv     NoDeals   FundsInvested   DistinctInvestors   ....

+== 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.
