SUPPLEMENTARY INFORMATION:
Table of Contents I. Introduction II. Proposal One III. Notice and Comment IV. Ordering Paragraphs
I. Introduction On March 11, 2021, the Postal Service filed a petition pursuant to 39 CFR
3050.11 requesting that the Commission initiate a rulemaking proceeding to consider changes to analytical principles relating to periodic reports.1
The Petition identifies the proposed analytical changes filed in this docket as Proposal One.
II. Proposal One Background. Proposal One is a request to change the methodology for estimating revenue, pieces, and weight for domestic products reported into the Revenue, Pieces, and Weight RPW
Report. Petition at 2. The Postal Service cites the introduction of numerous census system sources over the last 10
years as reducing the need to rely on Origin-Destination Information SystemRevenue, Pieces, and Weight ODISRPW sampling estimates. Id.
The Postal Service states that its proposed methodology would enable significant reductions in manual data collection and the accompanying costs, while maintaining statistical reliability.
Id. The Postal Service additionally filed under-seal materials related to RPW
data for competitive products.2
Proposal. The Postal Services proposal seeks to update its current RPW system used to generate the RPW
report filed quarterly with the Commission in conformance with 39
CFR 3050.25. Petition at 2. The current system relies on a variety of source systems, including the ODISRPW
probability sampling system.3 The Postal Services proposed methodology redesigns the non-digital sampling portion of ODISRPW and makes minor changes to the digital portion, along with a two-thirds for non-digital and 1 Petition of the United States Postal Service for the Initiation of a Proceeding to Consider Proposed Changes in Analytical Principles Proposal One, March 11, 2021 Petition. The Postal Service also filed a notice of non-public materials relating to Proposal One. Notice of Filing of USPSRM2021

one-third for digital reduction in sampling size. Id at 12.
The Postal Service notes that past reliance on ODISRPW for business decisions has been replaced by the alternative disaggregated data source Informed Visibility IV, addressing the Commissions previous concern that alternative disaggregated data sources be developed prior to reducing the sampling size of ODISRPW. Id. at 11.
Similarly, the current Service Performance Measurement SPM
system does not rely on ODISRPW
volumes, so service measurement would be unaffected by the proposed changes to ODISRPW. See id. at 1112.
The proposed updates to ODISRPW
include consolidation of non-digital sample areas from 189 to 10 to reduce the chance of the smaller sampling size creating strata with no usable tests. Id.
at 13. Mail characteristic stratification are defined uniformly at the national level, and sample data would be pooled across sample areas to ensure a sufficient sample size for each of the twenty strata. Id. The Postal Service additionally proposes using a ratio estimator for the non-digital sample using total reference volume across letters, flats, and parcels as the auxiliary variable to obtain national estimates from the sampled data. See id. Updates to the digital sample areas are limited to the same consolidation of sample areas, and an increase in the number of stratum from five to six. Id. at 16.
Overall, the Postal Service proposes to reduce ODISRPW sample sizes from approximately 31,000 to 18,000 tests per quarter. Id. at 17. The Postal Service justifies this reduction by the proposed methodology changes and the fact that much of the Postal Services mail product information, including RPW
reporting, now comes from census source systems. Id. The Postal Service would prefer to begin the reduced sampling starting July 1, 2021. Id.
Rationale and impact. The Postal Service justifies the proposed changes to ODISRPW as a comprehensive design that would reduce sampling without compromising the integrity of the RPW
program. Id. at 18. The Postal Service states that estimates from ODISRPW, when combined with census source RPW information, would provide reliable and consistent information. Id.
The Postal Service conducted simulation studies of the impact of the proposed changes and compared the results to census source data, and provides a table that shows the affected lines of the RPW report. Id. at 1820.
The Postal Service states that coefficients of variability impacted by the proposed change would grow from

2.3 percent to 2.9 percent quarterly, and 1.2 percent to 1.4 percent annually, noting that there is no universal standard for acceptable levels of variation. Id. at 20. The Postal Services states that it does not view the potential minor increases in variability for RPW
reporting as a cause for concern, and further states that it sees little or no practical impact of its proposal on the accuracy or reliability of estimates generated for the RPW report. Id.
III. Notice and Comment The Commission establishes Docket No. RM20213 for consideration of matters raised by the Petition.
