In 2018, NCPG commissioned Ipsos to conduct a U.S. national consumer study to examine the prevalence rates of various forms of gambling. The following points outline the research approach and methods used:

• An online survey was used to poll consumers throughout the continental United States, Alaska, and Hawaii. Online consumer response panels were the main source of samples used in the collection of surveys. This included panel sources from Ipsos and various other market research industry panel sources.

• All surveys were collected from November 8 – 29, 2018.

• Ipsos assisted the NCPG with the design of the survey instrument, and conducted all fieldwork management, including sample sourcing, collection, and hosting of the survey online.

• The survey was offered in English and Spanish.

• The survey was designed to allow for easy completion on any device type (e.g. computers, smartphone, and tablet).

U.S. National Sample

A national sample of 3,000 adults was collected, and was representative of the U.S. population fallout based on state population distribution as follows:

All Respondents	3000
NORTHEAST		East South Central
New England		Kentucky	41
Maine	13	Tennessee	62
New Hampshire	13	Alabama	45
Vermont	6	Mississippi	27
Massachusetts	64	West South Central
Rhode Island	10	Arkansas	27
Connecticut	34	Louisiana	43
Middle Atlantic		Oklahoma	35
New York	187	Texas	248
New Jersey	84	WEST
Pennsylvania	120	Mountain
MIDWEST		Montana	10
East North Central		Idaho	15
Ohio	108	Wyoming	5
Indiana	61	Colorado	52
Illinois	119	New Mexico	19
Michigan	93	Arizona	64
Wisconsin	54	Utah	26
West North Central		Nevada	28
Minnesota	51	Pacific
Iowa	29	Alaska	7
Missouri	56	Washington	69
North Dakota	7	Oregon	39
South Dakota	8	California	364
Nebraska	17	Hawaii	14

South Atlantic
Delaware	9
Maryland	56
District of Columbia	7
Virginia	78
West Virginia	17
North Carolina	94
South Carolina	46
Georgia	94
Florida	199

Quotas were established during fielding to ensure the 3,000 sample was also representative of key U.S. demographics such as gender, age ranges, and Hispanic/non-Hispanic proportions. The data was further weighted post-fieldwork to ensure a proper distribution based on educational attainment. All demographic figures were matched to figures from the U.S. Census Bureau.

State Samples

In addition to the 3,000 surveys nationally, individual state samples were ‘boosted’ to allow for state-by-state data comparisons.

Each state’s sample was boosted to an upper-end sample of 500 adults per state. Some states achieved fewer surveys due to smaller population and less availability of consumer panel sources. The final state-level samples, when adding the main national sample plus state boosts was as follows:

NORTHEAST		East South Central
New England		Kentucky	500
Maine	500	Tennessee	501
New Hampshire	501	Alabama	500
Vermont	401	Mississippi	500
Massachusetts	500	West South Central
Rhode Island	500	Arkansas	500
Connecticut	500	Louisiana	500
Middle Atlantic		Oklahoma	501
New York	500	Texas	501
New Jersey	500	WEST
Pennsylvania	500	Mountain
MIDWEST		Montana	500
East North Central		Idaho	500

West North Central		Nevada	500

Iowa	500	Alaska	379
Missouri	501	Washington	500
North Dakota	494	Oregon	500
South Dakota	490	California	501

South Carolina	500
Georgia	501
Florida	500

Sports Bettors

As a sub-set of both the main national sample, and each state sample, sports bettors were identified through a series of questions to assess which activities consumers have been involved with. This number constituted the “incidence” of sports betting within the general adult population.

The number of sports bettors within each state was also ‘boosted’ in order to allow for state-by-state data comparisons. The total number of sports bettors collected in each state was as follows:

NORTHEAST		East South Central
New England		Kentucky	199
Maine	146	Tennessee	202
New Hampshire	158	Alabama	200
Vermont	113	Mississippi	230
Massachusetts	198	West South Central
Rhode Island	171	Arkansas	204
Connecticut	200	Louisiana	247
Middle Atlantic		Oklahoma	233
New York	210	Texas	211
New Jersey	205	WEST
Pennsylvania	207	Mountain
MIDWEST		Montana	124
East North Central		Idaho	144

The precision of Ipsos online polls and surveys is measured using a credibility interval. In this case, the 3,000 U.S. nation sample has a credibility interval of plus or minus 2.0 percentage points for all respondents.  The credibility interval will be wider among subsets of the sample population, as follows:

• Sample of 1,000; credibility interval is +/- 3.5%

• Sample of 500; credibility interval is +/- 5.0%

• Sample of 200; credibility interval is +/- 7.9%

All sample surveys and polls may be subject to other sources of error, including, but not limited to coverage error, and measurement error.
