Made a (very) crude table with 2016 Census data for NB's big three southern cities.
It's interesting how you get a different story depending on the metric you choose. In some cases, the cities look like they're similar in size. In other cases, they don't.
I think the Economic Region metric, which we don't often talk about, helps address two recent discussions here.
Oromocto isn't in the Fredericton CA, but it is included in the Economic Region.
Route 15 between Shediac and Moncton is busy during peak times, because the Moncton-Richibucto Economic Region is the largest in NB and many of the people in the Moncton-Richibucto Economic Region but not the Moncton CMA happen to access Moncton by Route 15.
Here's the Dictionary for the 2016 Census, should you be wondering how any of the terms are defined:

Edit: Edmundston-Woodstock and Campbellton-Miramichi are the two other Economic Regions in NB. They sit at 77,578 and 154,351, respectively.
Another edit: Halifax, Avalon Peninsula, and PEI Economic Regions sit at 403,390 (3.3%), 270,348 (3%), and 142,907 (1.9%), population (and growth) respectively. While the NB Region boundaries are bit more nuanced (but probably not too controvertial), those of each of these Regions are exactly what they sound like.
The general trend in Atlantic Canada seems to be that the largest Economic Regions are also growing the fastest as a percentage of population - meaning they are further pulling ahead of the smaller Regions.
