+# Annual NTD Ridership by RTPA
+
+In response to... and the accompany the Monthly NTD Ridership Report, Caltrans is providing CalSTA with NTD Annual ridership by RTPA. 
+
+This report shows general ridership trends by Annual NTD Reporter by mode, and type of service for California RTPAs from 2018 to present. Unlinked passenger trips are reported, as well as the change from the prior year. For example, July 2023's change would be the change in July 2023's reported values against July 2022's reported values.
+
+## Definitions
+- **FTA**: Federal Transit Admisistration.
+- **MODE**: A system for carrying transit passengers described by specific right-of-way (ROW), technology and operational features. Examples: Bus, Cable Car, Light Rail.
+- **Monthly NTD Reporter**: Full Reporters that submit Monthly Ridership (MR) and monthly Safety and Security reports to NTD.
+- **NTD**: National Transit Database. A reporting system that collects public transportation financial and operating information.
+- **RTPA**: Regional Transportation Planning Authority.
+- **TOS**: Type of Service. Describes how public transportation services are provided by the transit agency: directly operated (DO) or purchased transportation (PT) services.
+- **UZA**: Urbanized Areas. An urbanized area is an incorporated area with a population of 50,000 or more that is designated as such by the U.S. Department of Commerce, Bureau of the Census.
+
+
+## Methodology
+Ridership data extract from NTD  via the [Service Data - Annual Data Tables](https://www.transit.dot.gov/ntd/ntd-data?field_data_categories_target_id%5B2551%5D=2551&field_product_type_target_id=1016&year=all&combine=). Then filtered for Reporters residing in California UZAs. These California Reporters are grouped by RTPAs, then aggregated mode and TOS. The processed data for each RTPA is saved to a public respository, see datasets below.
+
+
+## Frequently Asked Questions
+**Q: Which Annual NTD Reporters are in this report? Why are some Reporters missing from an RTPA?**
+
+Transit operators/agencies that aubmit annual reports to NTD are included in this report. Reporters that were previously Urban full reporters, but are currently not, may appear. This may result in Reporters showing zero or partial ridership data in the report. 
+
+If a Reporter is not a monthly reporter, or has not reported data since 2018, they will not appear in the report.
+
+Examples: 
+- Reporter A is an urban full reporter from 2019-2022, then became a reduced reporter for 2023. Reporter A's ridership data will be displayed for 2019-2022 only.
+- Reporter B is an urban full reporter from 2000-2017, then became a reduced reporter for 2018. Reporter B will be named in the report, but will not display ridership data.
+- Reporter C was a reduced reporter form 2015-2020, then became an urban full reporter and began submitting monthly ridership data to NTD for 2021. Reporter C's ridership data will be displayed for 2021-present. 
+
+
+**Q: Where can I download my RTPA's data?**
+
+Data from this report can be downloaded from the Cal-ITP public data repository, see `Fully Processed Data Download` below. A Google Account is required to access the repoisitory. Once logged in, navigate to `.....`, click the year-month you want to download, then click `download`.
+
+The data is a zipped folder of all RTPA data for the year-month.
+
+
+**Q: How can my RTPA/Agency meet the requirements of the SB125 Guidelines regarding how "to make publicly available a summary of ridership data"**
+
+Per the [SB125 Final Guildelines](https://calsta.ca.gov/-/media/calsta-media/documents/sb125-final-guidelines-a11y.pdf):
+>RTPAs are required to post a link to this report and data in a manner easily accessed by the public, so that ridership trends within their region can be easily reviewed
+
+Hyperlinking this report on your RTPA's/Agency's webpage is a common method to meeting this requirement.
