Property Tax in Decatur County

via TaxByCounty

Decatur County's effective rate of 0.488% sits marginally below Tennessee's state average of 0.511%, positioning it near the middle of the state's 95 counties. The county's lower median tax of $654 reflects both its moderate rate and relatively affordable home values.

Cost of Living in Decatur County

via CostByCounty

Decatur County stretches lowest incomes hardest

Decatur County's 18.6% rent-to-income ratio exceeds the national average, but what matters more is its $46,190 median household income—the lowest among comparable counties—making housing burdens especially acute. At $716 monthly rent, costs are manageable in absolute terms, but they consume a larger percentage of earnings than in wealthier regions.

Decatur ranks among Tennessee's poorest counties

With a 18.6% rent-to-income ratio slightly above Tennessee's 17.6% average, Decatur nonetheless faces distinct challenges rooted in its $46,190 median income—among the state's lowest. The $716 median rent beats the state average, yet represents a heavier proportional burden for residents earning significantly less.

Decatur offers cheapest rents in its cluster

Decatur's $716 rent is the lowest among its regional peers, undercutting Dyer County ($760), Crockett ($854), and Cumberland ($829). However, Decatur's lower incomes mean renters still allocate a higher percentage of earnings to housing than neighbors with slightly higher median incomes.

Decatur's tight household budget math

Renters dedicate $716 monthly while owners pay $552 for mortgages, seemingly affordable until divided against the $46,190 median household income. The median home value of $133,900 remains within reach, but qualifying for mortgages and maintaining other expenses proves challenging for residents earning near or below county median.

Decatur suits those with stable rural employment

Relocating to Decatur works only for candidates with guaranteed income above the county median or significant savings; nominal affordability masks income scarcity. Compare Decatur's numbers against better-earning counties like Dickson ($73,223) or Fayette ($84,764) to assess whether rural opportunity justifies the income trade-off.

Decatur County faces significant income gap

Decatur County's median household income of $46,190 trails the national median of $74,755 by $28,565—a stark 38% gap. This substantial shortfall places Decatur among the most economically challenged counties in the nation.

Among Tennessee's lowest-income counties

At $46,190, Decatur's median household income falls 22% below Tennessee's state average of $58,994, ranking it among the state's most economically disadvantaged counties. This positioning reflects limited employment diversity and dependence on declining rural industries.

Decatur's earnings lag all comparison peers

Decatur County's $46,190 falls short of every neighboring county examined, including DeKalb ($48,484), Dyer ($54,973), and Crockett ($59,049). The county faces the steepest earnings challenge among these rural communities.

Housing costs strain limited household income

Decatur's 18.6% rent-to-income ratio is manageable on paper, but limited absolute income of $46,190 constrains overall financial flexibility. Combined with limited high-wage job availability, households have minimal room for savings or investment.

Building wealth through community resources

Decatur County residents face significant income headwinds but can benefit from low housing values ($133,900) and affordable rents. Seek out local workforce development programs, entrepreneurship training, and financial literacy services to build skills that unlock higher-wage employment opportunities.

via RiskByCounty

Decatur's Risk Trails National Norms

Decatur County's composite risk score of 38.42 with a Very Low rating sits well below the national average, positioning it among America's safer counties. This low exposure provides residents meaningful protection from most disaster types.

Among Tennessee's Safest Counties

At 38.42, Decatur ranks meaningfully below Tennessee's state average of 52.45, placing it in the state's lower-risk tier. Only a handful of Tennessee counties enjoy comparable safety levels.

Safer Than Most Western Tennessee Peers

Decatur's 38.42 score is considerably lower than Cumberland (67.24), Crockett (52.58), and Dyer (86.58), though similar to DeKalb (25.48). The county benefits from lower exposure to wildfire and tornado risk compared to surrounding counties.

Water Quality in Decatur County

via WaterByCounty

Decatur County Maintains Perfect Compliance

The county boasts a Grade A for drinking water with zero health violations in the five-year lookback. Decatur County avoids the state average violation rate of 34.6 per 100,000 residents entirely. Public water systems here consistently provide safe, reliable service.

Healthy Waterways Outperform State Benchmarks

Only 23.5% of the 51 assessed water bodies in the county are impaired, beating the state average of 30.2%. The 2022 data shows that loss of stream-side vegetation is the leading cause of local impairment. Protecting these natural buffers is critical for maintaining current water quality.

Focused Monitoring in Targeted Locations

Seven monitoring sites across the county track essential water quality indicators. These sites have recorded 734 measurements over the past five years, with a focus on physical and inorganic properties. While the footprint is smaller than neighboring counties, it provides vital data on local metals and nutrients.

Gauging Gaps in Decatur County

There is currently no active USGS streamgage providing live discharge data for Decatur County. In the absence of real-time flow stats, residents should refer to the county's strong compliance and watershed health grades. Monitoring remains focused on periodic sampling rather than live telemetry.

Preserving Vegetation to Protect Local Streams

Local watershed data suggests that maintaining stream-side plants is the best way to prevent future impairment. Healthy vegetation filters out E. coli and prevents sedimentation from entering the water. Landowners can help by leaving natural buffers between their property and the water's edge.

Soil Quality in Decatur County

via SoilByCounty

Acidic Alfisols along the river

Decatur County features silt loam soils categorized as Alfisols. The average pH of 5.18 is lower than both the Tennessee state average of 5.35 and the national median of 6.5.

Sand and silt provide easy workability

With 27.7% sand and 50.0% silt, this soil is relatively easy to till and work. The 20.3% clay content helps ensure the soil doesn't lose nutrients too quickly during heavy rains.

State-average water capacity for plants

The organic matter content of 1.35% is lower than the state's 2.44% average. However, the available water capacity of 0.168 in/in is nearly identical to the state average, providing reliable moisture for vegetation.

Variable drainage requires careful planning

The soil is moderately well drained but falls into the C/D hydrologic group. This indicates that water can move slowly through the profile, making runoff management important for agricultural fields.

Forestry and farming in zone 7b

This soil-climate combination is excellent for timber production and row crops like corn. Adding organic compost can help boost the lower fertility levels for a thriving home garden.

Lawn Care in Decatur County

via LawnByCounty

Navigating High-Difficulty Turf Management

Decatur County is one of the toughest places for lawns, with a difficulty score of 32.7. The combination of intense summer heat and acidic soil makes maintaining a lush green space a year-round challenge.

Enduring Intense Heat and Heavy Rains

The county faces a staggering 64 extreme heat days per year, nearly double the state average. This high heat, combined with 57.1 inches of rain, creates a humid environment where turf diseases can easily flourish.

Managing Acidic Silt Loam Soil

Local soil pH sits at 5.18, requiring significant intervention to reach the preferred 6.0 range for most turfgrasses. The silt loam texture holds 20.3% clay, meaning it can become very dense and difficult for roots to penetrate.

Surviving 21 Weeks of Drought

The county is currently 100% abnormally dry after enduring 21 weeks of drought over the past year. High growing degree days (4892) mean grass grows fast but also consumes water quickly during these dry spells.

Choosing Heat-Tolerant Grass Varieties

Because of the extreme heat, heat-loving Bermuda grass is the most reliable option for this 7b zone. Ensure your lawn is established between the spring frost on April 5 and the fall frost on October 29.
