This sentence points out a shortcoming of per-capita statistics: in spite of their usefulness in comparing larger and smaller cities, these statistics may unfairly highlight small towns, whose modest population sizes can cause anomalies in the data.

(A) CORRECT. The expression For all their usefulness is a proper idiom; it is used to introduce a contrast. (For all his studying, he performed poorly on the exam.) The overall sentence is grammatically legitimate, with a single main subject (per-capita statistics) and a single main verb (shine) amid a series of modifiers and subordinate clauses.

(B) Despite is a preposition and must be followed by a noun or noun phrase; it cannot be followed by a clause, as it is here. The word and is inappropriate between per-capita statistics and especially crime rates. The word and indicates that the two connected items are “separate but equal.” This isn’t the case; crime rates are a particular kind of statistic, not separate from the idea of the statistics.

(C) The word because is illogical. The statistics are generally useful despite the fact that they can sometimes be misleading, not because they are sometimes misleading. Different, an adjective, cannot be used to describe sized; the adverb differently should be used instead.

(D) When facilitating illogically implies that per-capita statistics themselves can facilitate comparisons between cities. In addition, this sentence is a fragment, consisting only of the noun per-capita statistics and modifiers.

(E) For their usefulness does not have the same meaning as the idiom for all their usefulness. The latter indicates a contrast; the former does not.Different, an adjective, cannot be used to describe sized; the adverb differently should be used instead.
