34 first-half goals. 75 second-half goals. Italy 1990 split the goals that way across 52 matches, a 68.8% second-half share that stands as the most lopsided in World Cup history. It looked like an outlier at the time. Across every tournament since, it has started to look like a benchmark. Since 1990, 58.5% of all open-play World Cup goals have come after half-time. Before 1990, that figure was 55.0%. The gap is not enormous, but it is consistent, and it only moves in one direction.

Eleven tournaments don’t lie

The before and after contrast holds across eleven consecutive tournaments. Pre-1990 editions were noisy in both directions: 1938 went 53.3% first-half, 1978 split almost exactly evenly at 51.0% second-half. Since 1990, no tournament has come close to first-half dominance. The tightest split in the modern era was 2006, at 51.4% second-half. Every other post-1990 edition sits at 56% or higher. Something structural shifted around the time Italia ‘90 was being played, and it has held.

1990 and 1982: the two extreme cases

Italy 1990’s 68.8% is the record, but Spain 1982 sits close behind at 64.8%, with 92 second-half goals against just 50 in the first half across 52 matches. Two tournaments on the same soil, eight years apart, both skewed heavily toward the second half. Neither is fully explained by overall scoring volume: 1982 was actually a high-scoring edition at 2.81 goals per match, while 1990 was the lowest-scoring modern tournament at 2.21. The H2 dominance in both cases was driven by something other than sheer number of goals.

The recent floor: 2014, 2018, and 2022 cluster together

Three straight tournaments landed within a narrow band. 2014 was 60.1%, 2018 came in at 60.8%, 2022 matched 2014 exactly at 60.1%. All three ran to 64 matches and all three produced between 163 and 168 open-play goals. That consistency across different continents, different squad styles, and different tactical fashions suggests the modern game has settled at roughly a 60/40 second half split as its default state. The era of balanced halves is not coming back.

Why the second half pulls away

The substitution rules changed alongside the trend, and that is the simplest explanation. Before 1995, teams had two substitutions. From 1995, three. From 2022, five. Fresh legs after the break punish tired defences, and a team that is losing uses its substitutions more aggressively. Half-time tactical adjustments add to it: a manager gets 45 minutes to study a specific defensive setup, then rewrites the plan. The opening 45 minutes are for figuring the opponent out while the second half is for exploiting them.

The one ceiling the modern trend hasn’t moved

Italy 1990’s 68.8% has survived 32 years of increasingly fitness obsessed, substitution heavy football. Since that tournament, the second-half share has risen, but no single edition has touched 1990’s peak. The 2022 edition, with five substitutions now available, still finished nearly 9 pp short of it. A five-substitute tournament with 104 scheduled matches in 2026 will almost certainly produce more second half goals overall. Whether the share climbs back toward that 1990 ceiling is a different question, and three straight tournaments parked at exactly 60% suggest it won’t.

While 60% has become our predictable baseline, that chaotic 68.8% peak from Italia ‘90 is still standing.
