The countdown to the 2020 Census is officially underway. According to the latest Census data, Pennsylvania's population stands at more than 12 million 800 thousand. One year from now the process begins anew to count the number of people here and across the nation. One lingering issue is whether a citizenship question should be included-that's now up to the courts. Ensuring an accurate count will be led not only by the US Census Bureau, but by state agencies including Community and Economic Development.
