Americas Microcomputer Statistics Committee (AMSC and LAMSC)

The AMSC was officially formed in 1991 to collect vendor-reported PC shipment data and provide the aggregate totals to the participating members. In 2010, the AMSC expanded data collection to include the collection of PC shipment data for Latin America and formed the LAMSC as an extension committee

Because the AMSC reports are based on actual PC shipment data for the United States and Canada, this program provides a level of accuracy that is not available from any third-party sources. Consistent and reliable information about market size and growth allows participants to measure their company’s performance relative to the market in an objective manner. Since its formation, the AMSC has made a number of reporting program enhancements and has coordinated the exchange of data with other international PC statistics programs.

Benefits to Participants

The AMSC program provides participating members with the most accurate, reliable, and cost-effective PC market statistics available.

Committee members have fast access to MONTHLY data covering desktop and portable (business-marketed, home-marketed, and personal workstations) and server shipments on a monthly basis.  The program is in the process of also adding tablet shipments.

Each spring and fall, the AMSC also develops a three year consensus forecast that provides a detailed view as to market growth and trends by form factor and technology.

Country Coverage

The AMSC and LAMSC provides coverage for the United States, Canada, Brazil, Mexico and Rest of Latin America.

IPR’s Role in the AMSC

IPR has provided a variety of consulting services to the AMSC since the committee’s founding in 1991. In 2009, IPR assumed the role of Program Administrator, coordinating the collection and reporting of member data. Previously, IPR developed estimates of non-participant shipments based on multiple publicly available and proprietary end-user surveys, distribution channel surveys, and component shipment data.

Data Submission and Data Security

Submissions for the AMSC are due on the 10th workday following the close of each month to allow reports to be issued between the 15th and 20th workday.

On issues of data security, the AMSC and LAMSC bylaws are strict and are designed to avoid any possibility of participant data disclosure. Participant data submissions are made by code number. No company names are associated with the data. Participants may elect to split their data submission across several code numbers. Submissions may be emailed or uploaded via a secure site to the program administrator. Since all submissions are ultimately destroyed, there are no paper or electronic records of individual participant shipment history.

Committee Meetings

Meetings are generally held semi-annually at member company sites. The one day meetings address issues and topics of concern to the committee members and give them the opportunity to network with industry peers, receive presentations, and engage with analysts from leading research firms and other organizations. During these meetings, the three year consensus forecast is also developed.


AMSC and LAMSC membership is available to all personal computer manufacturers with sales in the Americas. All AMSC and LAMSC members receive full participant, nonparticipant, and total market statistics reports. Current AMSC and LAMSC members include Dell, HP Inc., Hewlett-Packard Enterprise, Intel, Lenovo, and Microsoft.

Associate AMSC and LAMSC memberships are available to manufacturers of components used in PCs sold in the Americas. Associate members receive only total market statistics reports.

In addition to the AMSC and LAMSC committees, members with worldwide PC shipments may also choose to join the EMS (Europe, Middle East, and Africa) and/or APMSC (Asia Pacific excluding Japan) programs.
