Economic Hurdles in Rural Utah

by Mark Knold

Utah is a geographically large state. Based on total area, it is the 13th largest state, implying there is room to spread out. Despite all this space, Utah’s population distribution is quite concentrated. According to the U.S. Census Bureau, Utah is the nation’s 9th most urbanized state. This dichotomy has shaped a state with two economic profiles — one urban, one rural. It can be challenging for a state dominated and prospering within the urban to extend its economic bounty to the betterment of the rural.

What is rural? It depends upon one’s objective behind the question. Most define rural by a visual scan of the landscape. A lot of open land and not many people — rural. Yet economically, the view can be different. An area may look rural, but if the economic vitality of its populace is strongly integrated with a nearby urban area, then this creates a different perspective. The latter is a preference of the federal government — an entity that often makes allocation or distribution decisions based upon economic factors.


No matter how one technically defines rural, the Governor’s Office recognizes a recent dichotomy in Utah’s economic prosperity. Since the Great Recession, Utah has had compelling economic success. Yet, most of this is concentrated in Utah’s urban centers. Portions of Utah’s rural communities are not seeing matching levels of success. Utah’s Lt. Governor recently observed, “Not all of Utah’s communities are full participants in this economic success. Many counties off the Wasatch Front are experiencing challenges.”

In response to this economic disparity, the Governor’s Office has launched the 25k Jobs initiative — an effort for businesses to create 25,000 new jobs in 25 Utah counties by 2020. With this spotlight on rural Utah’s economics, let’s take a look at some of these rural challenges.

To most, jobs deliver their income and means for living sustenance. Therefore, employment, and peripheral variables associated with employment, becomes the strongest proxy for measuring the Utah economy’s health. We will look at Utah’s counties through the lens of employment, unemployment, the labor force and how the industry structure speaks to the underlying performance of these variables.

A profile of job growth becomes a starting point. Economic performance needs to be viewed with a somewhat long lens. The Governor’s 25k Jobs initiative was not born from a short-term disorder, but instead is recognition of weak longer-term fundamentals. To illustrate this perspective, one needs to backdrop the short-term mechanics against the longer-term dynamics.

The County Job Profile chart is an intersection of the short-term trend with the moderate-term. Each county is a bubble, and the bubble size reflects job counts. The chart is divided into four quadrants. The quadrants tell the story of the intersection of the short and moderate-term trends (growth or contraction) and the general health of the county’s economy.


There are two axes of measure. First, the vertical axis represents the short-term. It is the percentage of county job change between 2015 and 2016. Above the horizontal axis is growth — below is contraction.

Second, the horizontal axis measures the moderate-term. It is the percentage of job change over the past five years (2011-2016). To the right of the vertical axis is growth — to the left is contraction. Where a bubble lies is the intersection of the short and the moderate term.

To illustrate, find Beaver County on the chart. Beaver aligns with around -4.0 percent on the vertical axis, and 8.0 percent on the horizontal axis. This says that over the past five years, Beaver County’s job count has grown by 8.0 percent, but over the past year it has contracted by around 4.0 percent. This implies that Beaver County’s economy may be slipping a bit. A one-year view would imply a problem. A longer-term view places this short-term setback against a broader perspective of overall prosperity.

The quadrant of concern is the Contracting quadrant. These economies have contracted over both the most recent year and the past five years. No matter how one wants to define rural as outlined above, all of these contracting counties identify as rural.

In-county jobs alone are not the complete picture. For example, a large percentage of Morgan County’s residents commute to Weber or Davis counties for work. If jobs are not being germinated in Morgan County, the county and its population can still prosper from its ties with the urban area.

An additional way to look at the economy is through the lens of the labor force. The labor force consists of those 16-years and older who are either working or looking for work. It is based upon where people live, not where they work. A worker living in Morgan County will be represented in Morgan County on the following chart (County Labor Force Change); yet, if they work in Weber County, their job is represented in Weber County on the prior chart. Adding this perspective helps to round out a county’s profile.

The structure of the County Labor Force Change graphic is the same as the prior chart. The area of vibrancy is the upper-right quadrant where the labor force is increasing. The quadrant of labor force contraction is the lower left. A decline in the labor force occurs when people become discouraged and leave the labor force — yet stay in the county, or when people leave the county altogether. Either way, a decline in the labor force signals a fundamental negative in the economic trend.

Depending upon the variables measured, a gain in one and a decline in another can both be positive. Job growth and an unemployment decline are both positive. To associate the positive with low unemployment, the quadrant message on the Unemployment Rate chart has been transposed.

Every month an unemployment rate is calculated for Utah and each of its counties. A county’s unemployment rate can be measured against the Utah statewide average unemployment rate. In the following graphic, county rates are mathematically compared against the statewide rate (seasonally adjusted), recorded and then summed across time.

For example, if a county’s unemployment rate is 5.5 percent and the statewide rate is 4.0 percent, then that county’s difference for that month is 1.5. If a county’s rate were to be 3.5 percent against the statewide rate of 4.0 percent, then the difference is -0.5. These monthly differences are tallied and summed. A high score speaks to a consistent and persistent unemployment rate above the statewide average. In other words, these are counties with a continuous environment of high unemployment.

The horizontal axis is a measure since 2000 and the vertical axis a measure since the beginning of the Great Recession (2008). The axis intersection is not at zero to isolate the “concern area” within the upper right quadrant. The statewide average is consistently close to the Salt Lake County average, so a sizeable number of counties will have sums slightly above the statewide average; yet, this doesn’t imply an unemployment problem. But the non-zero intersection is utilized to emphasize the counties that do have an outstanding unemployment disparity.

Across these various charts, a common group of rural counties emerge in the weak quadrant. These include Carbon, Emery, Garfield, Piute and San Juan counties; with Duchesne and Uintah hanging on the edge. There is a common theme that surrounds this grouping and it centers upon low economic diversity.

An economy’s ability to be consistently positive has a strong foundation in a diverse mix of industrial employment. Think of it in terms of “not putting all your eggs in one basket.” Economic diversity is spreading jobs across many baskets. Diversity is desirable because the overall economy is not dominantly influenced by one or a handful of industries whose poor performance weighs upon the whole.

A Hachman Index is an evaluation tool measuring to what degree an economy may or may not have all its eggs in one basket. In the Hachman Index, a measure of 1.0 means your eggs are well distributed across many industries. Conversely, numbers approaching zero point to a high concentration in one or a handful of industries.


Many of the counties that score low on the previous charts are the same ones on the lowest tier of the following Hachman Index chart. This chart represents the placement of economic diversity upon employment change of the past five years. A county will be placed high or low (vertical axis) on the chart depending upon its Hachman Index score. It will align right or left (horizontal axis) depending upon its five-year employment change. Metropolitan counties have higher economic diversity than rural counties — placing them higher on the chart. They are also further to the right on the chart, showing stronger employment growth. There can be individual exceptions, but the general theme is that lack of economic diversity is a foundational impediment to economic viability. Industrial diversity, though difficult to artificially induce, is a desired remedy to counter sluggish economic performance.

Lack of diversity does not mandate a poor economy. A reproduction of this chart five years ago would have placed Uintah and Duchesne counties still low on the chart, but their five-year growth rates would have been off the chart, needing arrows to point out beyond the chosen 40 percent horizontal axis limit.

Those economies are dominated by energy production. When energy prices are high, their economies can soar. When energy falters, they often do likewise. They are striking examples of economic outcome being determined by a dominant industry.

In summary, there is a dichotomy within the Utah economy between urban and rural. The urban economies are diverse and, therefore, more economically balanced; while many rural economies are not. With some rural counties the economic distinction is not a wide divide; but in the rural counties where the divide is pronounced, the underlying theme is often a low level of economic performance.

Bear River Location Quotients

Tyson Smith, Regional Economist

In the summer issue of Local Insights we discussed the value of economic diversity and the Hachman Index (a method used to measure industry diversification in the labor market)[1]. The article states that:

The Hachman Index is derived from the weighted average of the industry Location Quotients (LQ) in a region. A LQ measures the regional concentration of employment in a given industry relative to a larger geography. As a rule of thumb, an LQ of 1.2 or higher represents an industry with a relatively high concentration of regional employment, while a score of 0.8 or lower indicates sparse regional employment… Breaking the Hachman Index into individual components provides insight into the distribution of employment in a local economy.

Figure 2 in that article resembles the charts to the right, except that the data in the article was aggregated to the regional level. Combining the employment counts for all three Bear River counties obscures the concentration of employment in certain industries at the county level. This article sheds light on the relative density of employment in each county.

When examining the three charts, note the scale on the horizontal axis. In 2012, Cache County had very few location quotient outliers. Four industries were within the “normal” location quotient range, and only two industries had LQs greater than 1.2. Furthermore, the industries with above normal concentration of employment in Cache (manufacturing and educational services) registered LQs substantially lower than the highly concentrated industries in Box Elder and Rich counties.

Box Elder County had five industries in the “normal” LQ range, but three of the four high-density industries recorded LQs above 2. This means that the proportion of the workforce employed in manufacturing, transportation & warehousing and agriculture, forestry, fishing & hunting more than doubled the national percentage.

Lastly, Rich County had the lowest Hachman Index among the Bear River counties. Among the 10 industries that meet disclosure standards, only two industries had employment LQs in the “normal” range.

In Utah, there is a correlation between the size of a county’s labor force and the degree of industrial diversity in the county; in general, this means the more workers in a county the more diverse the economy of that county.  So it is not surprising that Cache County has less variance in its respective LQs compared to Box Elder and Rich counties.

Understanding the relative concentration of employment by industry lends some insight into the comparative advantages of a region. In terms of Bear River, we see that the labor economy is moderately diverse compared to other counties in the state.

Economic Diversity: Further Analysis of the Hachman Index

Tyson Smith, Regional Economist

In the summer issue of Local Insights we explored local area industry diversity using the Hachman Index. As stated in the article, many economists believe that economic diversification promotes stability in local markets. The article also touches on the difficulty of identifying an exact index value that denotes an appropriately diverse economy. One way to examine Hachman Index values is described below:

Click Image to Enlarge
“It is difficult to determine exactly what index value constitutes a highly diversified region when there are large differences in total employment [among the regions]. However, if a county’s Hachman Index ranks considerably higher than its total employment count – relative to the other counties in the state – that is an indication that the county is relatively diverse. Using this method reveals that Rich County had the fourteenth highest Hachman Index and the 27th largest employment base in the state, making it more diverse than counties of similar size. Conversely, both Box Elder and Cache’s index values ranked three spots below their total employment ranks of fifth and eighth, respectively.”

This simple comparative method highlights the correlation between the size of the workforce in a given county and the industrial diversity in that area. In general, counties with larger populations do not rely on one or two key industries for employment. On the other hand, small communities in less populous counties often exist because their region has (or had) a comparative advantage in a single industry. The relationship between employment count and economic diversity allows us to identify counties that are more or less diverse[1] than expected using the matching exercise in the chart to the right.




[1] Counties where the Hachman Index ranks more than two spots higher or lower than the Total Employment ranking are identified as “More Diverse” or “Less Diverse”, respectively. The "two spot" difference as a means of identifying notable incongruities does not represent a scientific methodology, it is only meant to give directional insight into the data.
