While North Dakota tops lists for its nearly nonexistent unemployment rate and the happiness of its residents, it lands on the low-end when it comes to its number of new cancer cases.
An average of 3,400 new cases of cancer were diagnosed annually from 2006 to 2010 in the state, according to the National Cancer Institute. That puts it at 32nd in the nation for highest incidence of cancer.
North Dakota’s incidence rate was about 450 cases per 100,000 people. Delaware topped the list with 514 cases while Arizona brought up the rear with 396 cases.
The graph below illustrates which types of cancer incidence rates are increasing and decreasing by annual percent change.
Breaking it down by North Dakota county for all cancer types, Sargent County has the highest incidence rate of cancer in the state with 600 new cases per 100,000 people per year from 2006 to 2010.
Here’s the top 10 counties with the highest incidence rates:
|Sargent County, ND||599.9|
|Griggs County, ND||565.3|
|Ward County, ND||515|
|Barnes County, ND||511.8|
|Foster County, ND||510.1|

|Renville County, ND||354.9|
|Kidder County, ND||354.6|

|McKenzie County, ND||338.7|
|Sheridan County, ND||293.5|
|Billings County, ND||*surpressed|
|Slope County, ND||*surpressed|
*Suppressed means the number of cases was so low the registry could not list them because it may compromise patients’ anonymity.
Obviously in a state as sparsely populated as North Dakota, the numbers seem a little inflated by the per 100,000 people measurement. For instance, Sargent County’s population during the time of the study hovered around 3,800 people.
Taking a look at the annual average counts gives you a better idea of how many new cases pop up per county.
In Sargent County’s case, the average was 31 cases per year. Cass County takes the top slot with an average 597 new cases. Case counts for all counties are included in the above North Dakota Counties document.
The top 10 counties by cancer case count are below. These numbers represent all types of cancer.
The counties topping the cancer count list unsurprisingly remain similar when looking at death counts. The top 10 list is largely unchanged with more populous counties near the top.
This document, North Dakota Death Rates, contains death incidence rates and counts for all cancers for all North Dakota counties.
Cancer deaths overall have been decreasing in North Dakota and nationwide. Below is the average annual percent change by cancer type.
If you want a more historical view, this graph shows cancer deaths peaked in the early 1990s and has since declined.
