Pennsylvania's Homestead Exclusion reduces property tax by:

The Homestead Exclusion is not calculated as a percentage of assessed value; a percentage-based approach would give larger absolute dollar benefits to owners of more expensive homes, which contradicts the equity goals of the program — the flat dollar amount structure was specifically chosen to avoid this outcome.

$15,000 statewide is incorrect because there is no single uniform statewide exclusion amount; while some districts may set their exclusion near $15,000, the amount is set locally by each school district and varies considerably across the commonwealth, making a fixed statewide figure factually wrong.

The 50% reduction for seniors describes a different program — the Senior Citizen Tax Relief (the 'Frozen Assessed Value' or 'Senior Tax Freeze' programs) or the state's Property Tax/Rent Rebate Program — not the Homestead Exclusion, which applies to all qualifying primary residences regardless of the owner's age.
