DATA QUALITY
CBDO Population Dataset
The list of CBDOs is highly representative of CBDOs alive and active from 2001 to 2019, with a special focus on a full representative list as of 2018, though it may not be comprehensive of the total sector. Additional CBDOs may exist that are not on our list, but the list contains 6,897 CBDOs alive between 2001 and 2019. It is a compilation of organizations from community development association membership lists, HUD funding recipients and grantees, and historical CBDO survey lists. See the project's technical report for a description of how this list was constructed and the criteria for organizational inclusion and exclusion.

2018 CBDO 990 IRS Data
The data in this dataset are a compilation of data from the Internal Revenue Service Statistics of Income Division (IRS SOI) and Amazon Web Services’ (AWS’) 990 public datasets for full 990 and 990-EZ filers. The dataset contains 5,720 organizations’ 990 data for filings in the 2018 tax year. The variables include key 990 tax variables, winsorized versions of those variables, financial health metric and ratio variables, and winsorized versions of those variables, as well as identifying information about the CBDO’s name, address, state, and region. The data have been cleaned and standardized. Variable definitions and metric source construction are in the data dictionary and are also described in the project's technical report.

CBDO Panel Dataset 2001-2019
The data in this dataset offer panel financial 990 tax data for 6,897 community-based development organizations (CBDOs) for every three years from 2001-2019. The data are a matched compilation of records from the NCCS Core Files, IRS SOI, and IRS AWS 990 public datasets for full 990 filers. (Note: the NCCS was used to source variables for 2001–2010 and SOI and AWS files were used for the observations in 2013–2019).
The resulting dataset offers selected core tax variables for each organization every three years (2001, 2004, 2007, 2010, 2013, 2016, and 2019), inflation-adjusted versions of those variables (2019 dollars), winsorized versions of those inflation-adjusted variables, and financial health ratios and metrics. This dataset does not represent the full universe of alive and active organizations in every year but was based on samples and comprehensive lists from three years: 2004, 2009, and 2018.

DATA LIMITATIONS
These financial data cannot do the following:
• offer a comprehensive list or picture of all CBDOs working within a given area or assign CBDO work to specific geographic service areas or populations as these data reflect the filing addresses for CBDOs, which are unrelated to service areas
• describe the specific type of activities CBDOs do, such as indicating whether they primarily focus on real estate development, community programs and services, or both
• measure the quality or effectiveness of CBDO work
• present a single objective measure or score of CBDO financial health or a numerical share of CBDOs that are healthy or unhealthy, because of the complex nuances of financial health, the importance of external factors for financial health (e.g., macreconomic, community, or local nonprofit market share factors) that are beyond the scope of this study, and the lack of a tested index or scale for the nonprofit sector as a whole or for CBDOs specifically
• describe the full financial experiences of the full CBDO field over time, because our analysis is based on samples of CBDOs drawn from 2004, 2009, and 2018 rather than a comprehensive universe of CBDOs created in each year from 2001 through 2019
• provide evidence on the reasons behind CBDO financial characteristics, because we did not collect or compile additional quantitative or qualitative data
