That's because the syntax is not properly specified. You must tell
destring to remove the comma then convert from str to num by using the
ignore option. See example below. If other characters were involved
like dollar sign, comma and period, you would specified: ignore("$ ,
.")

clear
input str10 malepop
"45,623"
""
"67,345,119"
""
""
"3406"
"56,670,986"
""
end

desc
destring malepop, gen(newvar) ignore(",")
desc

Hope this helps
