In recent years, East Liberty is being transformed, the Strip is being transformed, Lawrenceville is continuing to boom, more development is happening in Oakland and the Baum-Center corridor, South Side Works has shifted into a better mix of uses and is further developing, Downtown is continuing to thrive with an increase in night time population thanks to new residences and hotels, the river fronts are continuing to make progress, and on and on.
I'm as frustrated as anyone about the slow progress on the North Shore and in the Lower Hill, but that is fundamentally because development rights were stupidly given to pro sports teams as part of the public bribe for them to stay here.
Of course that isn't all Peduto, but he is proving, for the most part, to be a good partner and participant when it comes to development.
As for population--look again at those 2000 to 2010 numbers. The total population dropped about 29,000, but the 20s population increased 12,500.
The latest population estimate for the City suggest it may have lost a little over 1000 in population between 2010 and 2015:

That's already tracking way better overall than 2000 to 2010, and that is consistent with--in fact, basically requires--the young population to be growing a lot.
