Price Equity for Less-Resourced Countries: APS March, April Meeting, and DAMOP Registration Fees

To serve as a united, inclusive "welcoming global hub" for the diverse, worldwide physics community, APS announces a new, equitable registration pricing structure, available for in-person and virtual March, April, and DAMOP Meeting attendance.

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.

Price equity for the global scientific community underpins APS's mission to advance and diffuse the knowledge of physics for the benefit of humanity.

Pricing Tiers by Country

Registration for the March, April, and DAMOP Meetings will be available at the following scaled tiers:

  • 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$).

How to Qualify

Registrants with verified residency in LICs, LMICs or UMICs, will be automatically promoted to select their discount during the March, April, and DAMOP Meetings registration process. APS monitors the validity of all registrations.

Benefits to the Physics Community

March, April, and DAMOP Meetings are opportunities for all physicists, regardless of race, nationality, ethnicity, gender, and sexual orientation, to join together and share their research, learn from others, and collaborate. Equity in registration pricing is an important step in removing barriers of attendance for those who can both contribute to and benefit from a global scientific community of peers.

Process for Developing the Pricing Structure

A subcommittee within the APS Committee on International Scientific Affairs, in collaboration with APS executive officers, carefully constructed this new structure as part of a larger movement toward offering a “welcoming global hub” and serving physicists worldwide.

All APS meeting fees are evaluated each year to reflect the current costs of hosting each event.
