Where 115 U.S. Supreme Court Justices Are From

The Supreme Court of the United States (SCOTUS) presides at the highest level of America’s judicial system. It’s made up of a chief justice and eight associate justices who get confirmed by a Senate majority vote after a nomination by the president. While geographic diversity has been a key factor in presidential decisions, today’s justices can have ties to more than one state. For example, though the newly appointed Amy Coney Barrett was born in Louisiana, she identifies as being from Indiana, where she attended law school and lives now.

From the first Supreme Court Justice, John Jay in 1789, to the recent confirmation of #115, Justice Barrett, we’ll see which states have a lot of justices and which are without a single SCOTUS. Then we’ll investigate the shortest and longest tenures on the map below.

The data for the map came from Wikipedia’s list of the state of residence at the time of appointment. You can sort the map by a number of data points, perhaps most notably the president who nominated each justice, their confirmation year, when their tenure started, their position (whether chief justice or associate justice), and more. Let’s jump into it with the states with the most justices.

States Jammed With Justices

Thirty-one of the 50 United States have produced at least one Supreme Court justice. As is often the case, some states have more than others, with New York being the state with most. The Big Apple is where 15 SCOTUS members called home, though it’s not the only state from which multiple justices hail, as you’ll see below.

  • New York: 15 justices
  • Massachusetts: 9
  • Ohio: 9
  • Virginia: 8
  • Kentucky: 6
  • Maryland: 6
  • Pennsylvania: 6
  • Tennessee: 6
  • New Jersey: 5
  • California, Georgia & Illinois: 4

You’ll note from the map that five of these states are Northeastern, while four are located in the Southeast of the country. This may be because there were fewer states from which early justices could be appointed.

And while the other states may not measure up to those on the list above, Alabama, Connecticut, and South Carolina’s three justices aren’t anything to sniff at. Additionally, as the newest member of SCOTUS, Amy Coney Barrett is Indiana’s second confirmed judge. Other states with two include Arizona, Colorado, Iowa, Michigan, Minnesota, New Hampshire, and North Carolina. That leaves Kansas, Louisiana, Maine, Mississippi, Missouri, Texas, Utah, and Wyoming which have one each. Now that we know the states where multiple justices resided, let’s take a look at those sans Supreme Court justices.

States Without a Single SCOTUS

United States Supreme Court Building

Now, not every state has had a Supreme Court justice who calls it home. Some don’t have a single one. Those 19 states are:

  • Alaska
  • Arkansas
  • Delaware
  • Florida
  • Hawaii
  • Idaho
  • Montana
  • North Dakota
  • Nebraska
  • New Mexico
  • Nevada
  • Oklahoma
  • Oregon
  • Rhode Island
  • South Dakota
  • Vermont
  • Washington
  • Wisconsin
  • West Virginia

Seven (about 37%) of those are Western states, which becomes clear on the map. Even more specifically, the entire Pacific Northwest (Washington, Oregon, and Idaho) is without a single justice, along with the two non-contiguous states of Alaska and Hawaii. Now let’s move away from location towards the lengths of service.

Shortest & Longest Tenures

Supreme Court justices serve for life. From their confirmation until they die, resign, retire, or are impeached, SCOTUS members maintain their positions. How long that may be can differ from one justice to the next, though for the 106 non-incumbent justices, the average tenure was 16 years and 359 days.

The longest-serving justice was William O. Douglas. This 79th Supreme Court justice served from April 17, 1939 until he retired on November 12, 1975. In total, he served 36 years and 211 days.

The shortest-serving judge was John Rutledge. He served just 138 days between August 12, 1795 and December 28, 1795. Check out everything in between these two extreme tenure lengths by sorting the map. Speaking of, let’s see what more we can do with our maps.

Maps permit you to visualize your data geographically. But you can take that visualization one step further by incorporating photos or images into your maps. An example is our map of where Supreme Court justices are from in which we included portraits of each justice to better describe them.

Detailed steps are included in our blog post on how to Make a Map with Clickable Pop-up Infowindows and Images. It comes down to simply creating a column in your spreadsheet for the link of your images and selecting the proper options in the geocoder.

The 93 Island Nations of the World Mapped

Of the 195 countries around the world, almost half can be considered islands. To meet the definition, these must be non-continental land surrounded by water. Though these island countries all meet the water at every border, they can be very different.

Some are huge, others tiny, a few are ancient, and many are newer than you might guess. Importantly, 45 of the 93 countries are considered associated states, dependencies, or other notable territories, meaning that while they’ve declared their independence as countries, though it hasn’t been universally recognized as such. And as you’ll see on the map, they are all quite geographically distributed, but all of them qualify as island escapes.

We’ll cover the largest of the 93 total island countries, the smallest, and lots of other details about these places. While these island nations can be more susceptible to the effects of climate change due to their proximity to water, some house huge populations. Additionally, we’ll highlight the oldest (and youngest) of these isles and demonstrate how you can obtain a summary of all your map markers from the map below.

The map is based on this Wikipedia entry of island countries, which differentiates between widely-acknowledged countries and those that only consider themselves countries. You’ll also see each island’s size (one of the largest is 2.2 million km2!), with more details about individual islands below.

10 Largest Country Islands

Of the world’s established countries, 48 happen to be islands, AKA non-continental land surrounded by water. A reminder: the other 45 on the map aren’t universally considered countries. Let’s see which is the largest of these nations, along with the rest over 50,000 km2.

  1. Indonesia: 1,904,569 km2
  2. Madagascar: 587,041
  3. Papua New Guinea: 462,840
  4. Japan: 377,976
  5. Philippines: 300,000
  6. New Zealand: 268,680
  7. United Kingdom: 244,820
  8. Cuba: 109,238
  9. Iceland: 102,775
  10. Ireland: 70,273

Indonesia, the Philippines, and Papua New Guinea are clustered in Maritime Southeast Asia. To the North is Japan while two other island countries (the United Kingdom and Ireland) reside in the British Isles, not too far from Iceland.

Then there are the associated states, dependencies, and other notable territories that sprawl across hundreds of thousands of square kilometers. One of these is bigger than even the largest independent island country: Greenland. An autonomous territory of Denmark, Greenland’s 2,166,086 km2 is 1.14 times the size of Indonesia. As for the second largest of the associated state islands, Norway’s Svalbard is 62,045 km2. The rest range from 18,275 (New Caledonia) to only 12 km2 (Tokelau). But enough about the largest of these country islands, let’s scale down our focus to the smallest.

Smallest Isles

All the islands on the map may be countries but they come in a wide variety of sizes. Take Indonesia, the largest sovereign island country: it’s more than 90,000 times the size of the tiniest, noted on the list below.

  1. Nauru: 21 km2
  2. Tuvalu: 26
  3. Marshall Islands: 181
  4. Saint Kitts and Nevis: 261
  5. Maldives: 298
  6. Malta: 316
  7. Grenada: 344
  8. Saint Vincent and the Grenadines: 389
  9. Barbados: 430
  10. Antigua and Barbuda: 440

Of these independent island countries, half are located in the Caribbean: Saint Kitts and Nevis, Grenada, Saint Vincent and the Grenadines, Barbados, and Antigua and Barbuda. Now let’s move on from size to another metric.

Island Nations Population: Most & Least

Physical size isn’t everything. Other metrics make an island country stand out, like how many people choose to live there. The top ten most populated sovereign states have over 664 million residents combined, as you’ll see below.

Name Population Area (km2) Pop density (per km2)
Indonesia 267,670,543 1,904,569 138
Japan 125,710,000 377,976 337
Philippines 101,398,120 300,000 295
United Kingdom 65,587,300 244,820 246
Madagascar 26,251,309 587,041 35.2
Republic of China 23,550,077 36,188 633
Sri Lanka 20,277,597 65,610 314
Haiti 11,439,646 27,750 350
Cuba 11,245,629 109,238 102.3
Dominican Republic 10,878,246 48,442 208.2

This table may appear a lot like the list of largest country islands (after all, Indonesia still resides on top). However, the Republic of China (also known as Taiwan), Sri Lanka, Haiti, and the Dominican Republic were added in place of Papua New Guinea, New Zealand, Iceland, and Ireland when it comes to the largest populations.

And while half of the smallest island countries (size-wise) are located in the Caribbean, it’s also home to three of the most populated (10+ million each): Haiti, Cuba, and the Dominican Republic. In Maritime Southeast Asia, Indonesia and the Philippines are two of the most populated island nations. Puerto Rico is the most populous associated state or territory with 3,690,923 people.

On the other hand, the island country of Singapore is highly populated when its relatively smaller size is taken into account. Discover other densely populated islands on the map or continue to learn about the least populated.

Least Populated Country Islands

Those who live in any of the following lesser independent populated island countries likely all know each other, so let’s take a look.

Name Population Area (km2) Pop density (per km2)
Tuvalu 12,373 26 475.88
Nauru 13,635 21 649
Palau 20,000 459 43.6
Saint Kitts and Nevis 51,300 261 164
Marshall Islands 62,000 181 342.5
Dominica 71,293 754 105
Antigua and Barbuda 86,295 440 194
Seychelles 87,500 455 192
Kiribati 98,000 811 135
Federated States of Micronesia 101,351 702 158.1

Tuvalu and Nauru are the least populated country islands by a long shot. Tuvalu, which was the second smallest size-wise, is actually the least populated island while Nauru, the #1 smallest is the second least populated. Nauru is also one of the five islands with tiny populations located in Micronesia. Other islands that may be familiar from the smallest islands table include Marshall Islands, Saint Kitts and Nevis, and Antigua and Barbuda.

The folks with plenty of wide-open spaces (and the lowest population density) live in Iceland (3.1 per km2). Let’s move on from population size to another fact worth mentioning about the island countries.

Oldest of the Island Nations

Now let’s highlight the island countries that were either established or gained their independence so many years ago.

  • Japan (660 BC)
  • United Kingdom (1707)
  • Haiti (1804)
  • Dominican Republic (1821)
  • Cuba (1868)
  • Philippines (1898)
  • New Zealand (1907)
  • Republic of China (1912)
  • Ireland (1919)
  • Iceland (1944)

The Philippines gained separation from Spain on June 12th, 1898 and the island country later earned its independence from the U.S. in July of 1946. Both the Dominican Republic and Cuba also had two different dates of establishment. Then there are the newest nations.

Young Island Countries

As for the youngest of the bunch, East Timor is the only island country established in the 21st century. Other more recent additions to the island country roster are Brunei (1984), Saint Kitts and Nevis (1983), Antigua and Barbuda (1981), Palau (1981), and Vanuatu (1980).

Then there’s 1979, the year of island inclusion. Five island nations were established that year: Marshall Islands, Kiribati, Federated States of Micronesia, Saint Vincent and the Grenadines, and Saint Lucia. To see how you can better see them, read on.

Get a Summary of Your Many Markers

It’s easier to spot trends in your data when you can see it on a map. But sometimes, even with the visualization of a map, you’re faced with too many data points to gain insights. With 48 sovereign island countries and 45 associated or territory ones—some so small, as we’ve shown, you have to zoom in to get a good picture of what’s going on.








That is, unless you have summary markers to give you an idea of what’s below. A map with Cluster View enabled does just that. Learn more about how you can convert hundreds of markers into a reasonable number that still shares the underlying story or jump into it yourself with BatchGeo.

Map Locations Alongside City, County, or ZIP Borders

We use maps every day, both personally and professionally. While they can help navigate to the dentist or find nearby restaurants, they can be especially powerful when combined with your company’s data. You might map your customers, leads, and assets or even enlist a custom map to help you track your business proposals. When you give a geographic context to your spreadsheets, you can add a whole new dimension of understanding.

When you combine your locations with additional data and put them both on the map, even more is possible. For example, imagine if you could show your mapped locations—whatever they may be—alongside the boundaries and borders of a city, county, or zip code. In this post, we’ll walk you through how to do just that. By exporting your map from BatchGeo and importing it into Google Earth, you’ll be able to turn on the appropriate boundary layer(s) and see your data in a new way. Whether you wish to do so with counties to see which points are inside or outside each county or with cities or ZIP and postal codes, Google Earth has multiple border options, all of which we’ll demonstrate below.

Export Your BatchGeo Map

First things first, you’ll want to export your map from BatchGeo. Do this so that you can then import it into Google Earth to show the locations alongside your preferred boundaries—such as a city, county, or postal code.

But before doing so, you’ll want to have a map of your data ready. You can quickly copy-paste a list of locations from a spreadsheet to create a map.

Create A Map of Your Locations

Of course, the first step in any online mapping endeavor is to properly prepare your data. You’ll want an address and other location data within your spreadsheet, which might look something like this:

Then you can follow these simple steps to create your map:

  1. Open your spreadsheet
  2. Select (Ctrl+A or Cmd+A) and copy (Ctrl+C or Cmd+C) your data
  3. Open your web browser and navigate to batchgeo.com
  4. Click on the location data box with the example data in it, then paste (Ctrl+V or Cmd+V) your own data
  5. Check to make sure you have the proper location data columns available by clicking “Validate and Set Options”
  6. Select the proper location column from each drop-down
  7. Click “Make Map” and watch as the geocoder performs its process

The end result is an interactive map, like this sales example below.

Create KML File

With your map primed and ready, right-click and select the Export to Google Earth option, our automatic KML creator which allows you to export KML from Google Maps, or in this case, the Google Maps API BatchGeo uses to map your data.

You can learn more about our Excel to KML feature, which converts any spreadsheet into a shareable format used by Google Earth and other geographic tools. The next step will be to bring this downloaded KML file of your BatchGeo map into Google Earth.

Import into Google Earth

Now you’re ready to show your map’s locations alongside boundaries. The process involves adding your BatchGeo map into the platform that can show cities, counties, or zip codes: Google Earth.

While Google markets a “newer” web version, it doesn’t have the same boundary options as its desktop companion. Therefore, we’ll be using the desktop app most tend to associate with the platform. If you don’t already have the free Pro software, you can download it here.

Then, to import Google Earth KMLs, follow the steps outlined below:

  • Open Google Earth Pro on your desktop
  • Click File > Import… and select the KML file we previously downloaded from BatchGeo

With your BatchGeo locations transferred into Google Earth, we can now turn on our desired city, county, or ZIP boundary settings.

Turn on Google Earth’s Boundary Layer

To view the appropriate boundaries, we’ll take advantage of Google Earth Pro’s Layers dropdown, which has countless options. Our focus will be on city, county, and ZIP borders.

You can find both city and ZIP boundaries under US Government dropdown (under “More”).

City Boundaries in Google Earth Pro
Postal Code Boundaries in Google Earth Pro

As for county lines, these can be found in 2nd Level Admin Regions (under the “Borders and Labels” > “Borders” dropdowns). Simply check that box to see one or more of these boundary options going forward.

County Boundaries aka 2nd Level Admin Regions in Google Earth Pro

Of course, you can zoom in and out to see what side of the boundary any of your points lands on. This can be useful for sales zones or to confirm which area a customer lives in.
