Currently, all participants are on a listen only mode. Today's webinar is being recorded and the recording will be posted publicly. If you have any objections, you may disconnect at this time. Now, I'd like to turn the call over to your host for today and one of your presenters also for today, Vicki Mack.  \nThankyou. Hello, everyone. Thankyou for joining our session on creating American Community Survey Maps with R. My name is Vicki Mack, and I work in the American Community Survey office at the U.S. Census Bureau. I'm here with my coworker Jessica Klein, who works in the Economic Statistical Methods Division. I'd like to remind you that today's webinar is being recorded.  \nIf you would like to follow along with our webinar, we have posted the slides at the link you see here. The link to the slides will be or may already be posted in the chat. A recording and transcript will be posted on our website within the next few weeks at this same link. If you have any questions during the webinar, please post them in the chat section and one of our team members will try their best to respond to you as quickly as possible.  \nAt the end of this webinar, we will also verbally answer some questions that may have been missed in the chat.  \nFor today's webinar. I'll provide an overview of the American Community Survey for ACS and the data it provides. Next, I'll discuss some of the Census Bureau's tools for mapping ACS data and the pros and cons of using R as a mapping tool versus these other tools. Then I'll explain tools you need to get started with mapping ACS data in R, including the application programing interface or API, and the R packages and functions.  \nAfter that, Jessica will demonstrate how to map ACS data and R. Finally, I'll share resources for learning more about R and ACS data. TheACS is the premier source of detailed information about the nation’s people and housing. The survey samples approximately 3.5 million addresses each year, and 150,000 Group quarter residents. These data are collected continuously throughout the year to produce annual social, economic, housing and demographic estimates for communities throughout the 50 states, D.C. and Puerto Rico.  \nThe estimates cover more than 40 topics. The ACS collects this detail information each year that was previously collected by the decennial Census, each decade. Information from the ACS generates data that help inform how trillions of dollars in federal funds are distributed each year, supporting more than 300 no federal uses and countless non-federal uses. ACS data are timely because they are released the year immediately following the year in which they are collected.  \nThe ACS creates period estimates, which mean they represent the characteristics of the population and housing over a specific data collection period. The ACS releases estimates for one-ear and five-year period. After years of extensive testing. The ACS was fully implemented in 2005. The first ACS one-year estimates were collected in 2005 and released in 2006. The first five-year ACS estimates were collected between 2005 to 2009, and released in 2010.  \nThe ACS collects data across four key categories social, economic, demographic, and housing. Social characteristics include topics such as education, language spoken at home, and veteran status.  \nEconomic characteristics include such topics as commuting to work, employment status and income. The ACS also collects basic demographic characteristics such as sex, age, race, and Hispanic origin. Housing characteristics include topics such as computer and internet use, housing costs, and new topics added in 2025-electric vehicles, solar panels, and public sewer connectivity. Data for these new topics are planned to be released in 2026. These topics are used to produce more than 1000 tables for local communities each year.  \nThe ACS also provides data for more","cbCaiq8tjQQB5Y5o","https://ap.wps.com/l/cbCaiq8tjQQB5Y5o","pdf",137091,13,"English","# Overview of the American Community Survey (ACS)\n## ACS purpose, coverage, and release cadence\n# Mapping ACS data with R\n## Census Bureau mapping tools and trade-offs\n## APIs, R packages, and starting workflows","[{\"question\":\"What is the American Community Survey (ACS) and what kinds of data does it provide?\",\"answer\":\"ACS is the U.S. Census Bureau’s main source of detailed information on people and housing.
