Digitization at the National Archives

Indexing the 1950 Census: Request for Proposal

Description

This Request for Proposal (RFP) is issued to identify a partner to enter into a cooperative agreement with the National Archives and Records Administration (NARA) to create an index for data elements from the 1950 Census, which will be released to the public on April 1, 2022. Respondents will provide a proposal detailing how they will create the index per the requirements provided in this RFP. For the partner, NARA will provide access to download the full 1950 Census Dataset on April 1, 2022, which will precede public access to download the full dataset by approximately four weeks.

Background Material

Proposal Requirements

Respondents will provide a capability statement (20 pages or less and no marketing material) that describes their ability to provide an index of the required “Must Have” data elements from the digitized 1950 Census forms. Describe in detail how your solutions, tools, and/or processes will produce the index data. Report what level of accuracy as a percentage, ie. 97% accurate, your process will achieve and provide a detailed explanation of how you will measure, validate, and ensure that level of accuracy. Include details on the required data dictionaries. Identify the timeframe for producing the project deliverables. Include your organization’s points of contact.

The cooperative partner should propose terms for the license it will receive for the index and associated documentation and any corresponding restrictions on its use by NARA. See the Index Data Rights section for more information.

All submissions are due by October 1, 2021. Any questions regarding the RFP shall be submitted in writing to the NARA Point of Contact listed below by September 14, 2021. All questions will be anonymized and posted with responses as an addendum to this RFP.

Criteria for Selection

NARA will choose a partner based on the best value to the government, which will include consideration of the following factors:

Organization’s ability to produce the index and associated documentation per NARA’s requirements
Proposed restrictions on use, if any, for the index and associated documentation (See Index Data Rights)
Level of projected accuracy for the index data and quality assurance processes in place to ensure the projected accuracy is achieved
Timeframe for producing the index and associated documentation
Any additional offerings responders choose to propose that will benefit NARA’s mission or strategic goals

NARA will select a partner by September 30, 2021, and inform all applicants. NARA reserves the right to not select a partner.

Index Requirements

General Requirements for Indexing All 1950 Census Forms

The index data must be provided to NARA in CSV delimited text files that are no larger than 250MB for each state or territory. CSV files can be subdivided by county or other local legal subdivision, and if necessary by Enumeration District, to ensure no file exceeds the 250MB limit.

The index data set must include a data dictionary for each form as a separate text file defining each data element and providing any information necessary to effectively use the data.

Each index entry for an individual must include the NARA-provided image filename and the original NARA microfilm number where the individual appears.

All index entries must be provided in the language of the recorded responses. If there is any ambiguity of the language of a response, the index data must use the language of the form, which is Spanish for P93 “Censo de Población Y Viviendas: 1950 Puerto Rico” and English for all other forms.

Index Delivery Requirements

The index and associated documentation produced as a result of this work will be delivered to a NARA-provided S3 bucket in the Amazon commercial cloud account within 12 months of the 1950 Census cooperative partner release date of April 1, 2022.

Index Data Rights

The index and associated documentation produced as a result of the cooperative partnership will be owned by NARA.
