In the past, a person\u2019s political outlook was not a particularly reliable predictor of whether they would participate in surveys. Now it is. Polling organizations are implementing numerous strategies to combat this challenge. This presentation covers the nonresponse challenge from the perspective of Pew Research Center, a national nonpartisan polling organization. The talk will present data on the scope of the challenge in Pew polling, which includes an address-based-recruited panel and an annual multimodal cross-sectional survey. It will also cover novel ways that Pew is trying to reduce nonresponse bias.\r\n\r\nBio\r\nCourtney Kennedy is Vice President of Methods and Innovation at Pew Research Center. She supervises the Center\u2019s survey design and data science teams. Her research focuses on nonresponse, weighting, modes of administration and sampling frames. Kennedy has a doctorate from the University of Michigan and a master\u2019s degree from the University of Maryland, both in survey methodology. She received bachelor\u2019s degrees from the University of Michigan in statistics and political science.", "occurrence_notes":null, "guid":"134643-21874657@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/134643", "building_id":"1000145", "building_name":"Institute For Social Research", "campus_maps_id":"76", "room":"1430BD", "location_name":"Institute For Social Research", "has_livestream":1, "livestream_type":"zoom", "livetream_require_login":0, "livestream_id":"96808884937", "livestream_password":"177406", "livestream_link":"https:\/\/umich.zoom.us\/j\/96808884937", "cost":"", "tags":["Survey Methodology"], "website":"https:\/\/src.isr.umich.edu\/", "sponsors":[ { "group_name":"Survey Research Center", "group_id":"5063", "website":"https:\/\/src.isr.umich.edu\/" }, { "group_name":"Institute for Social Research", "group_id":"3285", "website":"http:\/\/isr.umich.edu" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/04\/event_134643_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/04\/event_134643_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/04\/event_134643_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/04\/event_134643_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/04\/event_134643_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/04\/event_134643_original-1.png" }, "occurrence_count":1, "first_occurrence":21874657 } }
