About this Poll
This survey of 500 likely Iowa Democratic Caucus voters was conducted between August 20 and August 24, 2015, and is based on a statewide random sample drawn from a list of registered Democratic voters who indicated they were very or somewhat likely to vote in their local Democratic Caucuses for president in six months. Each of Iowa's five areas and demographic information were determined from past contested Democratic presidential caucuses including 2008 and 2004, using a probability-proportionate-to-size method, which means that the phone numbers assigned to each county were proportional to the number of likely caucus voters. Iowa's 99 counties were grouped into five general regions. The margin of sampling error for results based on the total sample is plus or minus 4.4 percentage points. Error margins increase for smaller subgroups in the cross-tabulation document which follows. All surveys may be subject to other sources of error, including, but not limited to coverage error and measurement error.
