On average, how long did residents live in wood-frame houses?

The average lifespan of residents living in wood-frame houses in North Dakota, often cited as around seven years, reflects the historical context of housing during periods of rapid settlement and development in the state. Many early settlers constructed wood-frame homes using locally sourced timber, which was more readily available than other building materials.

These homes were sometimes built quickly and with less durable materials due to the pressing need for shelter amidst harsh weather and difficult living conditions. As families expanded, they often upgraded to more permanent structures or relocated in search of better opportunities, thus averaging about seven years of residence in these wood-frame houses.

This time frame encapsulates the migration patterns and social mobility typical of the population during that era, as well as the impact of environmental factors that often necessitated the frequent rebuilding or relocation of homes. Therefore, the correct answer aligns with both the historical living conditions and the cultural context of settlement in North Dakota.
