What is changing?
Lightcast is improving its postings deduplication processes that will result in more robust reporting on the number of postings a given company has.
When will this change take place?
For Canada the change is planned on 6th October
What will this change mean for me?
We are expecting the postings counts to change nationally as follows:
| Canada |
2018 | 0.5% |
2019 | -0.6% |
2020 | -0.4% |
2021 | -1.0% |
2022 | -3.3% |
1 Jan - 30 Aug 2023 | -1.0% |
Why are you changing the deduplication process?
Lightcast has invested in better postings classification. With this, we have taken steps to use these improvements as part of our deduplication process which has largely remained untouched since inception.
What are you changing in the deduplication process?
We are changing one item:
The input for Company Name. In the new deduplication we will use our most up to date company classifier to identify and normalize the company name.
Why am I seeing decreased numbers?
As we are better normalizing company names, we are able to use this to be able to better match and find duplicate postings within each company.
What does this mean for my analysis?
Users will expect to see some variations in specific company counts
As posting numbers per company have shifted due to better deduplication we have seen a proportional change in all other data elements, so customers may choose to recomplete some analysis due to this.
Looking at the change from a ranking/distribution standpoint we see the same/similar rankings in occupations, skills, titles and all other data points as we did previously.
