The early 19th century was a time of great change for New York, which had already cemented its status as America’s largest city.
The opening of the Erie Canal helped turn the city into a shipping powerhouse, and there was a building boom on the horizon. Cholera epidemics, fires, and riots swept through the city at various points.
This fascinating interactive map, from Esri, is a snapshot of New York City during the tumultuous time (1836 to be exact), overlaid on the modern-day satellite map.
Getting the Lay of the Land
The base map used above is the stunning “Topographical Map Of The City and County Of New–York, and the adjacent Country”, published by the prodigious mapmaker, Joseph Colton.
For easy viewing, the map’s legend is below:
This map includes all the usual features, such as roads and prominent buildings, but it also has some clever secondary information built in as well. For one, shading indicates ares that were more built-up at the time. There are also a number of visual techniques to indicate topographical features as well. After all, NYC wasn’t as extensive as it is today, and much of the land depicted in the map is still undeveloped.
The full map is well worth exploring as well, as there are a number of beautiful illustrations throughout.

The Big Picture: New York City in 1836
At this point in time, development in Lower Manhattan extended until about 14th Street, where buildings began to give way to open spaces. The city’s grid pattern was beginning to take shape, following the Commissioners’ Plan laid out in 1811. At the time, New York was anticipating massive growth, and the straightforward grid pattern was an efficient way to prepare the city for rapid expansion.
In the 1800s, fire was an ever-present danger for city dwellers. In fact, a major fire tore through Lower Manhattan a year prior to when this map was published.
Points of Interest
There are a number of points worth visiting on this map.
Transit Begins to Take Shape
In the 1830s, New York City’s first railroad line—horse powered for its first few years—connected Prince Street to the Harlem River, accelerating the city’s expansion northward from Lower Manhattan. This route is still recognizable today as the Harlem Line.
One very obvious difference between the two maps is how much land has been reclaimed along shorelines in the area. Battery Park City, on the west side of downtown, and the Brooklyn Navy Yard are two prominent examples of infill. Randall’s Island, located near the top of Manhattan, is also an interesting place to observe changes in topography. Randall’s Island is actually made up of three islands that were eventually conjoined in the 1960s.
This interactive map is a great place to explore changes to NYC’s shoreline over time.
Taming the Landscape
Midtown Manhattan is worth zooming into for a couple of reasons. First, the outline of Central Park is visible, although the park would officially be approved until almost 20 years later.
As well, this topographical map clearly shows the numerous outcroppings spread across the island. Manhattan was far from flat in the 1800s, and it took a tremendous amount of effort—starting with gunpowder, pickaxes, and horse-drawn carts—to level the land.
Looking at these historical maps is a reminder that the New York City we know today is the product of hundreds of years of human effort, and that cities continue to evolve over time.
The Most Fuel Efficient Cars From 1975 to Today
This infographic lists the most fuel efficient cars over the past 46 years, including the current leader for 2023.
The Most Fuel Efficient Cars From 1975 to Today
When shopping for a new car, what is the most important factor you look for? According to Statista, it’s not design, quality, or even safety—it’s fuel efficiency.
Because of this, automakers are always looking for clever ways to improve gas mileage in their cars. Beating the competition by even the slimmest of margins can give valuable bragging rights within a segment.
In this infographic, we’ve used data from the EPA’s 2022 Automotive Trends Report to list off the most fuel efficient cars from 1975 to today.
Editor’s note: This is from a U.S. government agency, so the data shown skews towards cars sold in North America.
All of the information in the above infographic is listed in the table below. Data was only available in 5-year increments up until 2005, after which it switches to annual.
|Model Year||Make||Model||Real World Fuel Economy (mpg)||Engine Type|
From this dataset, we can identify three distinct approaches to maximizing fuel efficiency.
Prior to 2000, the best way for automakers to achieve good fuel efficiency was by downsizing. Making cars smaller (lighter) meant they could also be fitted with very small engines.
For example, the 1985 Chevrolet Sprint was rated at 49.6 MPG, but had a sluggish 0-60 time of 15 seconds.
The 2000s saw the introduction of mass-market hybrid vehicles like the Honda Insight and Toyota Prius. By including a small battery to support the combustion engine, automakers could achieve good MPGs without sacrificing so heavily on size.
While the Insight achieved better fuel economy than the Prius, it was the latter that became synonymous with the term “hybrid”. This was largely due to the Prius’ more practical 4-door design.
The following table compares annual U.S. sales figures for both models. Insight sales have fluctuated drastically because Honda has produced the model in several short spans (1999-2006, 2009-2014, 2018-2022).
|Year||Insight Sales||Prius Sales|
The Prius may have dominated the hybrid market for a long time, but it too has run into troubles. Sales have been declining since 2014, even setting historic lows in recent years.
There are several reasons behind this trend, with one being a wider availability of hybrid models from other brands. We also can’t ignore the release of the Tesla Model 3, which began shipping to customers in 2017.
We’re currently in the middle of a historic transition to electric vehicles. However, because EVs do not use fuel, the EPA had to develop a new system called MPGe (miles per gallon of gasoline-equivalent).
This new metric gives us the ability to compare the efficiency of EVs with traditional gas-powered cars. An underlying assumption of MPGe is that 33.7 kilowatt-hours (kWh) of electricity is comparable to the energy content of a gallon of fuel.
The most fuel efficient car you can buy today is the 2023 Lucid Air, which achieves 140 MPGe. Close behind it is the 2023 Tesla Model 3 RWD, which is rated at 132 MPGe.
