49 Democratic National Convention delegates (41 pledged with 27 on district-level and 14 statewide; 8 unpledged). The number of pledged delegates won is set by the number of state delegate equivalents (SDEs) won
After a three day delay in reporting the votes, the Iowa Democratic Party announced that Buttigieg had been awarded two more delegates than Sanders, but Sanders had won the popular vote in the state. Most of the media outlets would say that Buttigieg would be the winner, but the Associated Press declined to declare who would be the winner until all recount voting processes had been finished. The official result and calculation of pledged delegates was delayed again by a further six days after the election as they needed to correct the results from 3.1% (55) of the precincts. Both Buttigieg and Sanders then requested a recanvass for 8.1% of the official results, which narrowed Buttigieg's lead over Sanders to 0.08 state delegate equivalents.
The caucuses would be controversial because of the delays in the reporting of the results. Much of the delay was as a result of the mobile application used to report voting totals. More controversy started because of the errors and continued changing in the calculation and reporting of the state delegate equivalents. The Iowa Democratic Party chair would resign on the 12 February 2020 because of the criticism of the reporting.
↑The number of pledged national convention delegates is determined by the number of SDEs won, however, a candidate must get at least 15% of the total vote to get statewide and district delegates or at least 15% of the vote in a congressional district to get district delegates from that district. Each precinct has a certain number of SDEs and allocates them based on how many caucus goers there are for each candidate at that precinct. However, the caucus's allocation is preliminary and gets finally decided on district and state conventions, with only candidates still running during the state convention considered for statewide delegates. Yet, differing from this Buttigieg and Sanders actually retained at least a few of their statewide delegates.
↑Originally placed fourth with 6 delegates. 8 of the 12 statewide delegates initially awarded to Buttigieg (2), Sanders (3) and Warren (3), who had withdrawn in the meantime, had to be reallocated to Biden as the sole remaining viable contender and were added to his own 2 statewide delegates at the state convention on June 13.
↑Original winner with 14 delegates. Due to his withdrawal in March, 2 of the 5 statewide delegates mathematically won by Buttigieg were reallocated to Biden at the state convention on June 13.

↑Falling short of 15% on state level and in three of four districts, Klobuchar only surpassed the threshold in one district and won 1 delegate there.
