It sounds like you are expecting a multi-value parameter (e.g. '123;234;345').

In this case you can use list comprehensions, the map() function or a loop:#List comprehension:
Pop_options = [int(p) for p in Pop_option.split(";")]

#Map function
Pop_options = map(int, Pop_option.split(';'))

#Loop
Pop_options=[]
for p in Pop_option.split(';'):
    Pop_options.append(int(p))

What exaclty is the user entering? Why do you split the string input? What do you mean by "I am not getting the desired datatype" - are you writing the value to a field and that is failing?

If they are just entering a number, i.e.4568

all you have to do is convert from a string to an integer:Pop_option_str = arcpy.GetParameterAsText(0)
Pop_option = int(Pop_option_str)

or to be on the safe side:Pop_option_str = arcpy.GetParameterAsText(0)
try: Pop_option = int(Pop_option_str) # try conversion
except ValueError: arcpy.AddError('Input was not integer...') # input was invalid...

If they are entering something more complex, you will need to provide more information to us before we can help you...
