Unlike many of small towns in North Dakota, Larimore has maintained a relatively stable population for the last forty years. Its close proximity to employment opportunities in Grand Forks and at the Grand Forks Air Force Base have cause many commuters to take up residence.
In the rural areas surrounding Larimore, population density is higher east of the town than west. Once mostly populated by yeoman farmers, many of these homestead farms are now horse ranches, hobby farms, or homesteads without notable agrarian use.
Although Larimore's residential population is largely unchanged, commercial business declined through the final decades of the 20th century. Downturns in the farm economy and increased shopping options in larger, nearby cities such as Grand Forks led to many business closures in Larimore. The business district has since "bottomed out" and many of the once abandoned buildings have either been renovated for other uses or demolished and replaced with new structures. Abandoned lots and empty, deteriorating buildings still dot much of the downtown area of Larimore.
This climatic region is typified by large seasonal temperature differences, with warm to hot (and often humid) summers and cold (sometimes severely cold) winters. According to the Köppen Climate Classification system, Larimore has a humid continental climate, abbreviated "Dfb" on climate maps.[10]
