What is happening and when?
In April 2025, Lightcast will be enhancing accuracy in the way we code to the ANZSCO taxonomy. At the same time we will update our systems to output the most recent version of the taxonomy. The new data will be avialable to via Snowflake from April 14th, and will be become the default in Snowflake on June 6th. It will be exposed in Labour Insight from June 9th.
What should clients expect?
All historic postings data will be better coded using the new system, so data will be consistent for time series analysis. Clients may want to rerun analyses as we are expecting to see shifts across occupations.
We will be coding postings to the ANZSCO 2022 taxonomy, so clients will observe some changes to the taxonomy and may also notice some changes in the number of postings coded to particular occupations.
Why are we doing this?
The existing classifier works well, we have estimated over 80% accuracy – But there is room for improvement. Currently, when errors are found, it can take a while to fix them. Our new classifier is quicker, even more accurate and easier to update with fixes or improvements.
We are making this change to bring our customers the best possible coding which will be derived from our flagship Lightcast Occupation Taxonomy coding that boasts close to 90% accuracy levels. The updated coding has more granularity and greater precision, distinguishing between different specialties and encoding the occupation accordingly.
Additional Information
More specific details on all the changes in the data will be published here soon in a full change report.
If clients have any concerns about the classification system or the output ANZSCO data please contact [email protected] - Our team will happily provide further details or clarification relating to individual occupations.
