Voilà à quoi on reconnaît un village en plein essor : les femmes ont du caractère !
Somewhat literally: This is what we recognise a fast-growing city by.
More naturally: This is what we come to expect from a fast-growing city.
I’m not sure how to intrepret the phrase "Voilà à quoi on reconnaît...". I’d also appreciate an example sentence or two that includes this phrase.
