Share of home-league minutes played by own under-21 nationals, 2025/26
Own under-21 nationals played 4.8 % of the La Liga’s minutes; the highest share among the peers is Netherlands’s 13.6 %.
Across 8 countries (country means over two seasons), ten points more under-21 share go with +13.94 more top-9 players per million (90 % HDI −4.93 to 33.09, R² = 0.22). Within countries, from one season to the next, the estimate is +1.56 (90 % HDI −1.29 to 4.33), n = 16 country-seasons. The share is measured; its association with the per-head count is not settled.

Across countries
How we know
Across the 8 countries (country averages over both seasons), 10 points more U21 share go with +13.94 more top-9 players per million (90 % HDI −4.93 to 33.09).
As an analytics question In numbers: share of domestic-league minutes played by players aged ≤ 21 at season start, 2025/26, by country's top flight.
What we did We counted every minute played in the league and looked at how many of them went to players aged 21 or younger.
Sources Share of all league minutes played by players aged ≤ 21 at season start, 2025/26, per domestic top flight.
What this means
Under-21 nationals played 4.8 % of the La Liga’s minutes in 2025/26. The between-country and within-country estimates above carry wide intervals and neither is a causal estimate, so the page describes where Spain stands on this measure; it does not show that a higher share would raise the per-head count.
What this does not show
Minutes for under-21s in lower divisions or on loan abroad, minutes for foreign under-21s, and whether any young player was ready for more minutes, which no table here measures.
