Clinton was awarded 700.59 state delegate equivalents and Sanders was awarded 696.82 state delegate equivalents, according to a statement from the Iowa Democratic Party.
Clinton declared victory in the caucus early Tuesday morning when the party was still waiting for results from a final precinct.
Correction: The post originally reported incorrectly that Clinton received 48.9 percent support. She actually received 49.8 percent support.
Clarification: The Des Moines Register reported slightly different delegate totals. We've updated with the official tally from the Iowa Democratic Party.
