Price Equity for Less-Resourced Countries

This year’s Meeting offers price equity for less-resourced countries. Scientists with verified residency in countries classified by the World Bank as lower-income countries (LICs), lower-middle-income countries (LMICs), and upper-middle-income countries (UMICs) will now benefit from tiered registration pricing to minimize a financial barrier to attendance.

Pricing Tiers by Country
Registration for the DFD Meeting will be available at the following scaled tiers as long as the funds set aside to support this effort remain available. Once all funds are distributed, these discounts will end:

  • LICs and LMICs will receive a 89% discount
  • UMICs will receive a 72% discount

APS developed these tiers using a ratio between the registration fees and the average GDP per capita (in PPP$).


Requests for cancellations will be honored through November 1, 2023, and processed minus a $50 administrative fee. There are no refunds after this date. Cancellations must be sent in writing to
