Upton Park is the fullest ground in England this season on average, whilst Villa Park is the emptiest in the Premier League.
Research undertaken by MyVoucherCodes shows that the Hammers' 35,000-capacity Upton Park ground has been 99.75% full on average throughout the season, a higher figure than any other club in the top four tiers of English football.
Much of that impressive attendance record will be down to the superb season the Irons are enjoying, with Slaven Bilic's side, inspired by London footballer of the year Dimitri Payet, sitting in fifth just a point off a spot in the top four.
It has been a fitting final season at the traditional Boleyn Ground for the club, with the Irons set to relocate to the Olympic Stadium for next campaign.
Meanwhile, whilst Upton Park has been packed to the rafters throughout the season, it is perhaps unsurprising that Villa Park has been the emptiest ground in the Premier League on average this season.
Aston Villa have been rooted to the bottom of the table for the vast majority of the season and have won just twice at home in the league all campaign long.
Their fans have responded to the often dire football and poor results on display by voting with their feet, with only 81% of the ground's 42,700 seats being full each match on average.
Villa are one of only two Premier League sides to average less than 90% attendance throughout the season, with another struggling side in Sunderland also failing to hit the mark.
The Birmingham club are likely to experience a further drastic drop in attendances when they almost certainly begin plying their trade in the Championship next season, with the league's average standing at just 65.5%
