Ohio Had a Very Wet 2018




If your yard has been a swampy no man’s land all year, there’s a reason for it. 2018 was one of the wettest years ever across the state. In some cities, almost every month featured above normal precipitation. Let’s take a look across the state to see how places fared in this extraordinarily soggy period.


Here were the final 2018 totals in major Ohio cities and how they rank since their records began.

Cincinnati: 55.90″ 3rd wettest since 1871.
Columbus: 55.18″ 1st wettest since 1878.
Cleveland: 51.47″ 4th wettest since 1871.
Youngstown: 50.97″ 2nd wettest since 1896.
Dayton: 48.99″ 10th wettest since 1893.
Akron: 48.46″ 5th wettest since 1896.
Toledo: 38.01″ 22nd wettest since 1871.

In big cities in Ohio, only Toledo managed to avoid having a top 10 wettest year. Columbus had its wettest on record, beating the previous record of 54.96″ set just a few years ago in 2011.

Locally in the Columbus metro, here were some other totals.
Newark: 56.01″
Marysville: 51.12″
Lancaster: 50.51″
Circleville: 46.66″
OSU Campus: 46.66″

Biggest Individual Precipitation Day and Rank
Cincinnati: 5.02″ on 8/16/2018, 2nd highest since 1871.
Youngstown: 3.50″ on 9/9/2018, 11th highest since 1896.
Dayton: 2.88″ on 4/3/2018, 24th highest since 1893.
Akron: 2.50″ on 9/9/2018, unranked.
Cleveland: 2.12″ on 11/1/2018, unranked.
Columbus: 2.06″ on 4/15/2018, unranked.
Toledo: 1.62″ on 3/1/2018, unranked.

Cincinnati had 2 days in the top 10, but most other cities had just constant rain rather than exceptionally high individual totals.

Total 2018 Measurable Precipitation Days and Rank
Youngstown: 191 1st most since 1896.
Akron: 180 1st most since 1896.
Cleveland: 177 8th most since 1871.
Columbus: 162 6th most since 1878.
Cincinnati: 151 7th most since 1871.
Dayton: 148 10th most since 1893.
Toledo: 142 16th most since 1871.

3 cities saw more than half their days with measurable precipitation. Columbus came in at just under 50%. This also had the unfortunate result of making most of the year feel unusually gloomy. Traditionally sunny months in the summer and fall were much cloudier than normal.

Total 2018 1″+ Precipitation Days and Rank
Columbus: 15 1st most since 1878.
Cleveland: 13 2nd most since 1871.
Cincinnati: 12 7th most since 1871.
Dayton: 11 6th most since 1893.
Akron: 10 5th most since 1896.
Toledo: 7 7th most since 1871.
Youngstown: 5 9th most since 1896.

Columbus had the most 1″ days of any year on record, and even beat every other major Ohio city.

Wettest 2018 Months
Cincinnati: 8.21″ in August
Youngstown: 7.91″ in September
Akron: 7.26″ in September
Dayton: 6.72″ in September
Columbus: 6.71″ in June
Cleveland: 6.68″ in July
Toledo: 5.91″ in May

No cities saw any of their months be even close to the wettest ever. There were not really any events with heavy flooding, either, except in February in Cincinnati, when the Ohio River reached the highest since the 1997 flood. There was also some scattered flooding from some tropical system remnants that passed through, particularly in September, but for the most part, it was just constantly wet from beginning to end in most places.

Cincinnati flooding in February, 2018.

One might ask if 2018 was merely a blip or part of a long-term trend in the state. Climate scientists have actually looked at this, and the state has indeed been getting both warmer and wetter over the last century or so, but the pace of both the warming and the increase in precipitation has been much faster since the 1970s. Many of the Ohio’s wettest years on record have occurred since 1990.

The Recovery of Downtown vs Cleveland and Cincinnati Part #2- Update




Part #2 looks more specifically at the Downtown area of the 3-Cs.

**Updated with 2017 data.

First, let’s look at the total Downtown populations since 1950.

This graph, I think, will surprise most people. The first surprise is that downtown populations in 1950 were not nearly as high as most would have you believe. Cincinnati did have almost 22K people there, but even a city like Cleveland had less than 10K, and that was during the absolute peak of its city population. Another surprise is that Columbus was not always the lowest populated downtown and was more populated than Cleveland’s in 1950. Finally, the last surprise is that while all the downtowns are now growing, Columbus has regained 2nd place and Cleveland has seen the most growth so far.

What about tract trends for the downtowns? Well first, here are the population trends for each downtown.



Individual census tract population figures are based on the latest Census estimates for 2017. They are most likely too low or too high in some cases. For example, the city of Columbus estimates the current Downtown population FAR HIGHER than what the Census has them, and the significant drop in one of Cincinnati’s tracts is most likely incorrect. However, because the Census numbers are considered to be the most official, that’s what I’m using. Still, I expect wide differences when the physical counts come out for 2020.

Here is the total population change by Downtown.

Finally, I wanted to look at more of the downtown area than just the central business district. “Downtown” for many includes more areas than that and may be a “Greater Downtown Area”, the measurement between the full 1950 boundaries and just the CBD.

Here are the tracts I considered to be the Greater Downtown area for each city.

Cincinnati: 2, 7, 9, 10, 11, 263, 264, 265, 268
Cleveland: 1033, 1036, 1042, 1071, 1077, 1078, 1082, 1083, 1084
Columbus: 21, 22, 29, 30, 32, 36, 38, 40, 42, 52, 53, 57

And the graph for the population of these tracts since 1950 through 2017.

Cincinnati reached it’s lowest population for the past 60 years for this area in 2000 and has grown since. Cleveland’s greater downtown had bottomed out in 1990 and had the fasted growth during the 2000s, although that seems to have slowed some since 2010. Columbus managed to maintain the highest population in its greater downtown, bottomed out in 2000 and has grown since.

All this shows is that the Downtown, and the surrounding areas, are seeing a resurgence in the 3-Cs for the most part.




The Recovery of Downtown vs Cleveland and Cincinnati Part #1- Update




**Updated and reposted from last year.

Columbus’ downtown has seen many many changes, especially over the last decade. Developments like the Arena District, Columbus Commons, the Scioto Mile and more have brought new life to the area. Dozens of new restaurants and shops have opened in recent years, with more on the way. Larger developments coming up include the redevelopment of the Scioto Peninsula, Confluence Village- complete with a new Crew Stadium- and at least 3 new mixed-use towers. All of this has led to rising population, with estimates population by the city near 9,000. So the question I was wondering is how has population been changing not only in Columbus’ downtown, but in comparison to Cleveland and Cincinnati. Both of those cities have also seen major projects in their downtown cores and are seeing an uptick in their downtown populations.

First, I examined the 1950 city limits for all three cities. This was the last census year before sprawl really took hold and changed the city dynamics and growth patterns. 1950 is also when most cities in Ohio reached their peak urban population, so I thought it would be interesting to see how those old boundaries had changed over the years. I went to the US census website and began to look up all the census tracts that existed in each city in 1950. Those would represent my base area that I would use to see the changes in the city core. All of the 3-Cs have grown beyond those 1950 boundaries, especially Columbus, but these areas were the hardest hit when the urban decline came the last 50-60 years as the suburbs grew. Looking at how these areas changed is both sobering and perhaps hopeful as well.

All 3-Cs saw population decline between 1950 and 2010. Columbus’ decline which much less severe than the other 2, but it followed the same general trends. Since 2010, both Cincinnati and Columbus have seen growth within the 1950 boundary.

1950 Boundary Population Change 1950-2017
Cincinnati: -223,097
Cleveland: -539,907
Columbus: -134,562

1950 Boundary Population Change 2010-2017
Cincinnati: +2,392
Cleveland: -6,000
Columbus: +6,566

1950 Boundary Population % Change 1950-2017
Cincinnati: -44.3%
Cleveland: -59.0%
Columbus: -35.8%

1950 Boundary Population % Change 2010-2017
Cincinnati: +0.9%
Cleveland: -1.6%
Columbus: +2.8%

In Cleveland, the rate of loss had gradually been slowing down since the 1970s, but suddenly skyrocketed again in the 2000s. I’m not sure what exactly caused this. The double recessions made it more difficult for people to move, so if anything, the losses should’ve not accelerated. Cleveland lost over 90,000 people in its urban core from 2000-2010, the highest lost by % and total of any Ohio city, and one of the highest in the country.
In Cincinnati, population loss had peaked in the 1970s and the rate of loss fell substantially the following decade. However, the past 2 decades have actually seen a gradual acceleration of losses. The 2000-2010 period saw the second biggest total loss for the urban core, but there has been a significant turnaround (if estimates are correct) and the city is seeing growth now.
For Columbus, it’s been the opposite picture. Like the other 2-Cs, losses peaked in the 1970s. Since then, the urban core losses have been in gradual decline. The 2000-2010 period had the smallest rate and total loss of any decade the past 65+ years, and since 2010, there has been net growth.

So interesting results, but these numbers don’t show any trends of what’s going on inside the 1950 boundaries, especially not the relatively small part that would be the downtowns. So let’s break the numbers down a little more to the tract level.

# of Tracts in 1950*
Cincinnat: 107
Cleveland: 201
Columbus: 48

*The number of tracts changed from 1950 on as some were split or consolidated. This made it more complicated, but luckily the Census gives lists on how tracts changed over time, so one can figure out what tract became what and reasonably keep up with the same boundaries that existed in 1950.


So with this breakdown, we can see more of the trends within the 1950 boundaries. In Cincinnati, a long decline was followed by a recovery in 1990, only to have the next 20 years show an increasing decline. The 2010 census showed the fewest number of tracts growing on record. This is the worst performance of the 3-Cs. Cleveland also had a steep decline followed by a recovery, but it too declined more at the last census, but not nearly to the low point it reached in the 1970s and 1980s.

Meanwhile, Columbus also faced an initial steep decline and barely had any tracts growing during the 1970s. Since then, the trend has been up. The 16 growing tracts in 2010 were the highest since the 1940s. This is the best performance of the 3-Cs, and Columbus had the highest % of growing tracts in its core. Still, those 16 represent less than 1/3rd of the total tracts within the 1950 boundaries. However, in the case of all 3 cities, the 2010-2017 has greatly increased the number of growing tracts. This suggest that the urban core of every city has been improving this decade. The more than 68% of all 1950 area tracts growing in 2017 is by far the highest of the 3 cities.
In Part 2, we will look only at the specific downtown areas.




The Recovery of Ohio’s 3-C Downtowns: Revisit

A little more than 4 years ago, I posted numbers on how Columbus, Cincinnati and Cleveland were recovering in their urban cores. See that post here: http://allcolumbusdata.com/?p=289 and here: http://allcolumbusdata.com/?p=312 That post has proven to be one of the site’s most popular. I figured it was time to take a look at their continuing changes.

You can see by the chart for the 1950 Boundary population, the urban core of each city, that all 3-Cs suffered population losses post-1950. However, the rate of losses gradually declined, and 2 of the cities, Columbus and Cincinnati, appear to be growing in this boundary since at least 2010. Cleveland continues to lose.

This is shown further by the chart below.

As far as the actual Downtowns of each, here are the population trends.

For the most part, population declines in the 3-Cs peaked around 1980, give or take a decade. Since then, all of them have seen increases, with Cleveland seeing the most rapid increase and Cincinnati the least. Columbus has seen steady, but increasingly rapid growth with each subsequent decade since 1980.

Here is the chart for Downtown growth by decade.
