The four monthly business application series for Puerto Rico are now part of the Monthly Business Formation Statistics standard data product. This product was first released on March 12, 2024 as an experimental data product.

This product provides timely and high-frequency data on business applications. It measures business initiation activity as indicated by applications for an Employer Identification Number (EIN) on the IRS Form SS-4. The Monthly Puerto Rico Business Application Series use the same methodology as the existing Monthly Business Formation Statistics Application Series and therefore are combined.

A historical data series of monthly business applications for Puerto Rico are available from July 2004 to August 2025 and will be published monthly going forward. The Puerto Rico Business Applications Series are not included in U.S. or Regional Business Applications Series.

The Census Bureau has reviewed the monthly data product (including Puerto Rico) to ensure appropriate access, use, and disclosure avoidance protection of the confidential source data (Project No. P-7515311, Disclosure Review Board (DRB) approval number: CBDRB-FY25-0219).
