Aruch HaShulchan, Laws of Tzedakah, 251:8

The matter which has been clarified, that one’s parents precede others (when distributing your resources as a form of tzedakah), only applies when one does not have one’s own necessary needs (i.e. providing for your parents is only considered tzedakah when you sacrifice your supply of necessary resources.) If you have sufficient resources, then giving some to your parents absolutely does not fall under the realm of tzedakah, as it is written in Chapter 250, “A curse will be brought upon one who provides one’s parents from the money set aside for tzedakah.”... It is clear that the poor of your city precede the poor of another city; this rule applies even when the poor of your city are ignoramuses and the poor of another city are scholars. And our principle of “One with wisdom precedes your friend” only applies when both are residents of the same city. This is derived from our rule that your relatives precede others, even if (your relatives) are ignoramuses, as it is written, “not to ignore your own kin.” (Isaiah 58:7).....[Translation by AJWS]
