Hi @Arun Dharan
I'm a newbie to REI, but I lived in Allentown from 2001-2019, now live about 40 mins north. Allentown has some very rough areas, but wonderful areas as well, just like any metro area. Allentown is the 3rd largest city in PA, and it is the largest city that makes up what is called the Lehigh Valley. (https://en.m.wikipedia.org/wik...
I say all of that because the Lehigh Valley is a growing area. The areas surrounding Allentown are very safe. Bethlehem is a very trendy town, some people are saying that trend might be developing in Nazareth also. Easton, just along the border of NJ has potential, but also some extremely rough areas as well. Whitehall is where a lot of the largest shopping centers are located, including the mall. The Lehigh Valley has route 22 where the Lehigh Valley International Airport is located off of (22 and Airport Rd.) and interstate 78 runs close by which is a major route to NJ and NY. Add to that the PA turnpike northeast extension which will take you to Philly.
There is a lot of warehousing that is being built all around the Lehigh Valley because of those major highways, it has become a huge shipping hub. And its economy still grew in 2020 despite the strict lockdowns the Governor of PA mandated.
Here is a Google search on Lehigh Valley Growth.

Just some extra information to consider.
Best of Luck with everything.
