Voici ce à quoi on peut s’attendre would be the closest answer to the question in your title.

You later mention Recognize and Expect, which have two different meanings.

• Somewhat literally: This is what we recognize a fast-growing city by. =
  Voici ce à quoi l’on reconnait une ville en plein essor.

• More naturally: This is what we come to expect from a fast-growing city. = Voici ce à quoi on s’attend d’une ville en plein essor.

Voilà à quoi on reconnaît feels more like something you would say with enthusiasm.

Imagine you are a manager and you just saw an employee achieving a particularly difficult task, you turn to the other employees and say:
Voilà à quoi on reconnaît un bon employé!

Voilà à quoi on reconnaît un village en plein essor : les femmes ont du caractère ! = That’s how you identify a booming village, … !

Voici ce à quoi l'on reconnait une ville en plein essor. is more neutral, objective. = “You can identify a booming village by …”
