After eliminating repetitions, 94 occurrences were left, which were classified by hand, yielding 71 animate pronouns, 11 inanimate pronouns and 12 unclassified occurrences (for lack of sufficient context to recover the antecedent of the pronoun with certainty).
at least 76% of usages of they were animate; we assume the percentage of animate usages of the other pronouns to be even higher.
