Illegal school registrants, by the numbers

* The Upper Darby School District, which borders Southwest Philadelphia, said it had more than 1,000 outside families try to register kids in its schools between June and September.

* An overwhelming majority of those outsiders came from Philadelphia, the district said. Of those families, 654 nonresident students slipped through the cracks and were registered.

* Lower Merion School District, which shares a City Avenue border with Philadelphia, last year took to court 11 families with children illegally registered in its schools.

* Radnor School District, 20 miles west of Philadelphia, found 12 out-of-district students in its schools. Most were Philadelphians, district officials said.
