1. nobility - in French: 'la noblesse' (less than 1% of the French population in 1789)
2. clergy - in French: 'le clergé' (about 1% of the French population in 1789 - the vast majority such as poor priests, made up the low clergy)
3. commoners (everybody else) - called in French: 'le Tiers Etat' - representing nearly 98% of the population. More than 90% of the French population were poor peasants or day laborers)
Hope that helps
