Taxonomy is an international classification system with three different
locales: the U.S. English locale which
includes terms and definitions that are appropriate for subscribers in the
The majority of terms in the Taxonomy represent services that are offered in both countries under the same conditions and thus have identical data elements in the two English language locales. There are, however, spelling differences that must be accounted for, occasional differences in what services are called in the two countries with resultant variations in term names and use references, and differences in the way services are managed or delivered which may lead to variations in definitions. When differences occur, the Canadian English version of the term is modified creating two variants of the same record. U.S. subscribers see the U.S. English version and Canadian subscribers, the Canadian English one.
There are also a number of individual services that are only available in one country or the other; and large service systems like the courts and public assistance programs which vary enough that different sets of terms are required in the U.S. and Canadian locales for adequate representation.
Canadian French locale is a French language version of the Canadian English
locale and references Canadian English term names and definitions.
The choice of locale is particularly important in the Search function because only terms active within the locale are retrieved and displayed. To change the view of the Taxonomy that is being displayed, simply click on change next to Viewing beneath the Log in/Log out button at the top of the page and select the locale you wish to see. Once marked, the original choice persists until changed. Printed Taxonomy reports and XML files are also locale-specific, but depend on the locale in which they were run, not the locale setting on the website.
Thank you for your interest in obtaining or renewing your 211 HSIS taxonomy subscription
211 LA is preparing to launch delivery of the 211 Human Services Indexing System (HSIS) (formerly the 211 LA Taxonomy) via an API. The API will enable licensed vendors and licensed users to receive real time updates to the HSIS taxonomy. As part of the transition to delivery via API, the current process of providing an XML download will be retired in January 2024. 211 LA is working with its licensed vendors to enable integration of the API within their applications. We are targeting to have our licensed vendor transition completed by January 2024.
The 211 HSIS website is also being updated. The updates will continue to support the existing filtering functionality and “how-to” guides you enjoy today as well as additional features including enhanced search functionality.
Below is a table summarizing the new subscription tiers related to the Website and HSIS taxonomy:
