French percentage agreement: 30 % des personnes ont or a?

Choose French verb agreement after percentages, distinguish personnes from population and le taux, and complete data statements with a clear reference.

In short

Write 30 % des personnes ont répondu. Both 30 % and personnes point to a plural verb here. With a singular complement such as population, agreement can follow the collective noun or the percentage, depending on the intended focus.

Accorder avec un pourcentage

1 · 30 % des personnes: use the plural

For this construction, ont is the correct choice. Treating the whole written expression as one statistic does not make the verb singular.

30 % des personnes ont répondu.30% of the people replied.

2 · A singular collective can control agreement

Agreement with the singular complement is common when it presents the group as a whole.

30 % de la population a répondu.30% of the population replied.

3 · A plural percentage can control agreement too

With a singular collective complement, plural agreement can foreground the numbered proportion. Both readings exist; choose a clear focus.

30 % du personnel ont suivi la formation.30% of the staff took the training course.

4 · Find the head in le taux de…

In le taux de participation, the subject is le taux. A nearby percentage does not replace that singular head.

Le taux de participation, qui est de 30 %, a augmenté.The participation rate, which is 30%, has increased.

5 · Carry the reference into adjective agreement

When referring to the women or people named by personnes, use feminine plural adjectives and participles.

30 % des personnes interrogées sont satisfaites.30% of the people surveyed are satisfied.

6 · Les and ces make the percentage plural

A plural determiner before the percentage requires plural agreement, even with a singular complement.

Ces 20 % du budget seront consacrés à la formation.This 20% of the budget will be devoted to training.

7 · With 1 %, identify what you mean

Below 2%, the percentage itself is singular. A plural complement can still control plural agreement when the focus is on those people.

1 % des personnes ont demandé un entretien.1% of the people requested an interview.

1 % du budget sera réservé à la formation.1% of the budget will be set aside for training.

8 · Keep an omitted group recoverable

When the group is already known, keep agreement connected to it. Write a space before % in French.

Parmi les personnes interrogées, 30 % sont satisfaites.Among the people surveyed, 30% are satisfied.
