13. A non-transitory computer-readable storage medium for transcribing text appearing in imaged documents to an electronic file, comprising processor-readable instructions configured to cause a processor to: receive an image of a document, wherein text appears on the document and the document is a census document; analyze the text appearing in the image of the document; identify questionable text, wherein the questionable text is identified at a confidence level less than a threshold confidence level and the text is associated with a data category; access a similar content database, wherein the similar content database comprises a plurality of records comprised of information identified from a plurality of analyzed documents; determine that the document is related to a record of the plurality of records; analyze the related record to identify a string of candidate text associated with the data category from the related record as a replacement for at least a portion of the questionable text; cause the string of candidate text to be presented as a choice for replacement of the questionable text to a user, wherein the string of candidate text is identified based on the related record; receive a selection of the choice for replacement from the user; replace the unidentified text with the string of candidate text; and store the string of candidate text in a digitized document.
