The U.S. Census data and boundaries are subject to changes, with human-drawn boundaries being ever-changing and sometimes resulting in unexpected results. Geographies used by the Census Bureau include legal boundaries defined by law and statistical boundaries defined by the Census Bureau for data collection and presentation purposes. These boundaries can be affected by mistakes, changes, and resurveying, leading to issues like shoreline clipping where data boundaries extend beyond the physical shoreline. The Census Bureau maintains legal boundaries up to 3 miles offshore for administrative purposes but does not require them for statistical data dissemination. When mapping population at the county-level, using data from the latest 5-year estimates can help overcome holes in maps due to rural areas with insufficient populations being omitted from surveys. Understanding the Margin of Error (MOE) is crucial when working with Census and American Community Survey data, as it provides a 90% confidence interval for measurements. Additionally, there are instances where census data may not accurately represent reality, such as in cases like Central Park having only 25 reported residents, leaving room for interpretation and caution when using Census data for real-life decisions.
