If you use census data, then you are likely aware that the Census Bureau is applying a new form of privacy protection to Census 2020. What will it look like? How will it impact your existing workflows? To help answer these questions Esri has built feature layers for eight levels of geography so that you can explore how census data are likely to change for 2020. As the Census Bureau works diligently to fine tune their methods for privacy protection, they need feedback from data users like you<\/a>! Your input can help improve the Census 2020 data products.<\/em><\/strong><\/p>\n

The 2020 Census brings a new era of privacy protections with the implementation of differential privacy<\/a>. Differential privacy is a \u201cformal privacy\u201d approach that provides proven mathematical privacy assurances by adding uncertainty or \u201cnoise\u201d to the released data. This disclosure avoidance technique determines the amount of noise necessary to balance privacy loss and accuracy via mathematical formulas. Census 2020 will be the first large-scale application of this new privacy system. View this blog<\/a> for more information on the reasoning behind the implementation of this new privacy technique and how Esri is helping data users prepare for the impacts of differential privacy.<\/p>\n

To help data users prepare for this shift, the Census Bureau is currently releasing Census 2010 Demonstration Data Products that provide the public with a sneak peek at what the 2010 raw data would look like after being pushed through the Disclosure Avoidance System (DAS). As this new system is still under development, different versions of the demonstration products have been released. These releases are planned to continue periodically until the 2020 DAS is finalized. This gives the public the opportunity to perform analysis and provide feedback to the Census Bureau.<\/p>\n

This graph illustrates the goal of the DAS – finding a balance between between
\n<\/b>two desirable but incompatible features: accuracy and privacy<\/b><\/p>\n"},{"acf_fc_layout":"image","image":{"ID":966561,"id":966561,"title":"accuravy_v_privacy","filename":"accuravy_v_privacy.png","filesize":29957,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/08\/accuravy_v_privacy.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/esri-demographics\/local-government\/differential-privacy-in-the-census-census-2010-demonstration-products\/accuravy_v_privacy","alt":"","author":"6491","description":"","caption":"","name":"accuravy_v_privacy","status":"inherit","uploaded_to":966551,"date":"2020-08-05 02:10:06","modified":"2020-08-05 02:10:06","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":1277,"height":720,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/08\/accuravy_v_privacy-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/08\/accuravy_v_privacy.png","medium-width":464,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/08\/accuravy_v_privacy.png","medium_large-width":768,"medium_large-height":433,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/08\/accuravy_v_privacy.png","large-width":1277,"large-height":720,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/08\/accuravy_v_privacy.png","1536x1536-width":1277,"1536x1536-height":720,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/08\/accuravy_v_privacy.png","2048x2048-width":1277,"2048x2048-height":720,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/08\/accuravy_v_privacy-826x465.png","card_image-width":826,"card_image-height":465,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2020\/08\/accuravy_v_privacy.png","wide_image-width":1277,"wide_image-height":720}},"image_position":"center","orientation":"horizontal","hyperlink":"https:\/\/www.census.gov\/about\/policies\/privacy\/statistical_safeguards\/disclosure-avoidance-2020-census.html"},{"acf_fc_layout":"content","content":"

To better facilitate analysis from the public, Esri has published the demonstration products as feature layers. Each set of layers is designated based on the corresponding data release dates from the Census Bureau. The provided layers contain select critical variables from both the original Census 2010 Summary File 1 (SF1) release and Census 2010 with differential privacy applied.<\/strong><\/p>\n
