下载 SVGTennessee 地图能看出什么
Tennessee divides into 95 counties, and the state has been thinking of itself in three parts for so long that the division is written into its constitution and drawn on its flag. East Tennessee is the Appalachian end — ridges, valleys and the Cumberland Plateau, with Knoxville, Chattanooga and the Tri-Cities strung between them. Middle Tennessee is the Nashville basin and the highland rim around it, and it is where almost all of the state's recent growth has gone: Williamson, Rutherford, Wilson and Sumner counties have been among the fastest-growing in the country. West Tennessee is flat delta farmland running down to Memphis, which sits in the far corner of the state in Shelby County. A county map of Tennessee is nearly always a picture of those three Grand Divisions and of the four metros pinned to their corners.
Tennessee 的三种画法
数值是比率时给区域填色，是计数时用大小不同的标记。把这两者用反，是数据地图最常见的误导方式。
什么时候该画 Tennessee 地图
Your data is reported by Tennessee county
Department of Health indicators, Department of Labor and Workforce Development figures, Department of Education report-card data, Boyd Center population projections and Division of Elections returns are all published by county.
You are showing a rate or a share
Unemployment rate, uninsured share, opioid dispensing rate, graduation rate, share of the vote, median household income. A rate is already adjusted for how many people live in a place, which is what shading a region needs.
You want to show the Grand Divisions
East, Middle and West are meaningful units here in a way regions in most states are not — they have different economies, different politics and different histories. On a county map the three-way split is visible without drawing a single boundary.
You need a blank map to print or fill in
Tennessee history is a required school subject and the 95-county map is a standing exercise. The free outline above prints cleanly at any size.
什么时候不该画 Tennessee 地图
You are mapping totals rather than rates
Shade by a raw count and the map is Shelby, Davidson, Knox and Hamilton dark and everything else pale. Use symbols or bubbles sized by the count instead.
Your unit is a city or a metro
Nashville and Davidson County share one government, but Memphis is smaller than Shelby County, Chattanooga smaller than Hamilton, and the Nashville metro reaches across thirteen counties. Mapping a city figure onto a county shape will overstate it every time.
The measure follows the terrain rather than the boundaries
Flooding, forest cover, air quality on the Cumberland Plateau and Tennessee Valley Authority reservoir effects all follow topography and watersheds. County lines cut across all of them.
Only a few counties have data
Pickett, Van Buren, Moore, Hancock and Lake counties each have around five thousand residents or fewer, so suppressed cells are routine in health and education releases. A map that is mostly grey is a worse bar chart — rank the counties you do have.
如何制作 Tennessee 地图
从表格到发布上线，一步一步来。
Download the blank map, or start from the template
The free outline above is a plain SVG of all 95 counties — print it, or drop it into a document. To build with data, open the PlotSet Tennessee (counties) template, which comes with sample data already bound.
Prepare a county column and a value column
One row per county: the county name or its five-digit FIPS code in the first column, your number in the second. Tennessee's state code is 47, so every county code starts 47 and no leading zero can be lost.
Upload or connect your data
Import a CSV or Excel file, paste from a spreadsheet, or connect a Google Sheet so the map can be refreshed when the source updates.
Pick the style that fits the measure
Shade the counties for a rate, or switch to symbols or bubbles for a count. Same geography, same data, different encoding.
Choose a colour scale on purpose
Sequential for a low-to-high measure, diverging only when a real midpoint exists — the state average, zero change, a 50 per cent line. Four to six steps read more precisely than a smooth gradient.
Publish, embed or export
Publish for a live interactive map with a tooltip on every county, or export a PNG, SVG or PDF for a report or a deck.

地点列应该长什么样，以及去哪里找现成能对上的数据。
The Mc and De spellings are where joins break
McMinn, McNairy, DeKalb and Van Buren are written several different ways across state and federal files — with a space, without one, and with varying capitals. This map's geometry carries them as "Mc Minn", "Mc Nairy", "De Kalb" and "Van Buren", so normalise case and spacing on both sides of the join, or match on FIPS.
Three counties share a government with a city
Nashville and Davidson County have run as one metropolitan government since 1963; Lynchburg is consolidated with Moore County and Hartsville with Trousdale County. City-level and county-level figures for those three are the same number, so using both in one chart double-counts.
Half the county names exist in other states
Washington, Jackson, Madison, Monroe, Montgomery, Warren, Wayne, Franklin, Lincoln, Greene, Jefferson, Union, Perry and Marion are all Tennessee counties and all names used elsewhere. Any multi-state file must be filtered to state 47 before joining, or rows from Missouri and Georgia will land on Tennessee shapes.
Tennessee borders eight states
Only Missouri touches as many. It matters for regional analysis: the Tri-Cities reach into Virginia, Chattanooga into Georgia and Alabama, Memphis into Mississippi and Arkansas, and Clarksville into Kentucky. Several of the state's metros are mostly out of state, so a Tennessee-only map cuts them in half.
Where to get Tennessee county data
The Boyd Center for Business and Economic Research at UT is the usual first stop for population and economic series; the Department of Health, the Department of Labor and Workforce Development, the Department of Education, the Secretary of State's Division of Elections and the Census Bureau's ACS all publish county tables directly.
Tennessee 地图上的常见错误
Shading counts instead of rates
Shelby and Davidson counties together hold about a fifth of the state. Shade a raw count and the map is those two counties, whatever the measure was supposed to be. Anything that grows simply because more people live somewhere should be a sized symbol.
Treating Nashville and Davidson County as separate rows
They are one government and one set of numbers. A file that carries both will either double-count the largest county in Middle Tennessee or leave one of the two rows unjoined and grey.
Letting the big rural counties carry the picture
The plateau and delta counties cover a lot of paper and hold few people, so on a shaded map they take visual weight their populations do not justify. Readers read area as importance — say so in the caption.
Suppressed data drawn as zero
With several counties under six thousand residents, health and education releases blank out small counts as a matter of course. Import those cells as empty rather than as 0, or the emptiest counties will read as the healthiest ones.
Using a rainbow colour scale
A sequence of hues has no natural order, so readers cannot tell high from low without checking the legend on every county. Use one hue, light to dark.
