mySidewalk has a couple different ways that data is managed and updated in the Data Library. Some data is kept current automatically (by a process we call stomp but it's essentially a replace) but some data is added on to over time. Examples of these include the Decennial Census and BLS Labor Statistics. For the data that 'adds' you have an option to keep the data that you originally chose or elect to "keep data current" inside the component.
After you choose data, click the Style tab.
Check the box next to "Keep Data Current"
At this point you will no longer be able to edit the data values you have selected. If you want to edit them, uncheck the box and re-build the data you want, then check the box again. This will ensure that your data will be updated as the Data Library is updated.
As we mentioned at the very beginning, some data will change regardless of your choice (because we replace it when new data becomes available). They are as follows (previous versions will not be available):
CDC WONDER pooled years.
EPA EJ SCREEN
Change over time between 2 ACS estimates
US Census ACS 5-year Estimates
Projected Census data
LODES 10-year change over time
School Proficiency Index
You can always check the Data Catalog for more information about an individual data source. Click the 'i' icon next to data and then click "Click here for more info."
Not everyone has access to this feature. Talk to your CSM about what options are available to you.
