Mode share by trip miles and trip frequency in Chicago and Cook County

Two tables in this post. Data from the Chicago Metropolitan Agency for Planning’s 2008 Travel Tracker Survey. Download source file (pdf).

Table 1. Number represents share of trip miles taken by that mode. So in Central Chicago (which seems to comprise neighborhoods as far north as Uptown and as far south as Hyde Park), 1.4% of all trip miles are by bike. If 1,000 people take 100 trips of 2 miles each, then 2,800 miles will be by bike.

Frequency of Chicago women riding their bikes to work is down

UPDATE: I added data from years 2005-2007 to complement existing 2008-2009 data in Table 1 as well as a visual representation. I have also added data from the 3-year estimates to Table 2.

UPDATE 01/20/11: Added the most recent 3-year estimate that the Census Bureau released in January 2011 to Table 2.

In September 2009, I wrote about “what the Census tells us about bicycle commuting” and a couple of days ago I compared Chicago to Minneapolis and St. Paul.

I want to update readers on the changes between the 1-year estimate data reported in that article (from 2008) and the most recent 1-year estimate data (from 2009). Percentages represent workers in the City of Chicago aged 16 and older riding bicycles to work.

Table 1 – Bicycling to work, 16 and older, 1-year estimates

Year Total MOE Male MOE Female MOE
2005 0.7% +/-0.1 0.9% of 621,537 +/-0.2 0.4% of 541,013 +/-0.1
2006 0.9% +/-0.2 1.2% of 645,903 +/-0.3 0.7% of 563,219 +/-0.2
2007 1.1% +/-0.2 1.4% of 656,288 +/-0.3 0.7% of 574,645 +/-0.2
2008 1.0% +/-0.2 1.5% of 657,101 +/-0.3 0.5% of 603,640 +/-0.2
2009 1.1% +/-0.2 1.8% of 651,394 +/-0.3 0.4% of 620,350 +/-0.1

View graph of Table 1. MOE = margin of error, in percentage points.

We should be concerned about the possible decrease in the percentage of women riding bicycles to work, especially as the population size increased. The margin of error also decreased, thus suggesting an improvement in the accuracy of the data. There have already been many discussions (mine, others) as to why it is important to encourage women to ride bicycles and also what the woman cycling rate tells us about our cities and policies. If the decrease continues we must discover the causes.

But Table 1 doesn’t tell the full story.

As Matt points out in the comments below, the number of surveys returned for 1-year estimates is smaller than that from the Decennial Census. Therefore, I took a look at the two 3-year estimates available, each having a larger sample size than the 1-year estimates (see Table 2). The data below seem to show the opposite change than seen in Table 1: that the number of women bicycling to work has increased. The crux of our quandary is sample size. The sample size is the number of people who are asked, “How did this person usually get to work LAST WEEK?”

Table 2 – Bicycling to work, 16 and older, 3-year estimates

Click header for data source 2005-2007 2006-2008 2007-2009
Total workers 1,203,063 1,230,809 (+2.31%) 1,291,709 (+4.71%)
Males bicycling to work 7,549 9,014 (+19.41%) 11,014 (+18.16%)
Females bicycling to work 3,474 3,741 (+7.69%) 3,542 (-5.62%)

The number of discrete females who bike to work has decreased in the most recent survey (2007-2009) while the total number of workers 16 and older has increased, giving females bicycling to work a smaller share than the previous survey (2006-2008). We must be careful to also note the margin of error for females bicycling to work is ±499.

Matt suggested that sustainable transportation advocates “push for higher sampling” to reduce “data noise” and increase the accuracy of how this data represents actual conditions. I agree – I’d also like more data on all trips, and not just those made to go to work. Household travel surveys attempt to reveal more information about a region’s transportation.

One of the two overall goals of the Bike 2015 Plan is “to increase bicycle use, so that 5 percent of all trips less than five miles are by bicycle.” Unfortunately, the Plan doesn’t provide baseline data for this metric, but we can make some inferences (there will probably be no data for this in 2015, either). The CMAP Household Travel Survey summary from 2008 says that the mean trip distance (for all trips) for Cook County households is 4.38 miles (under five miles). The same survey says that for all trips, 1.3% were taken by bike. These can be our metrics. *See below for men/women breakdown. Note that no data for “all trips” exists for the City of Chicago.

We will not achieve the Bike 2015 Plan goal unless we do something about the conditions that promote and increase bicycling. Achieving the goals in the Bike 2015 Plan is not one group or agency’s responsibility. The Plan should be seen as a manifestation of what can and should be done for bicycling in Chicago and we all have a duty to promote its objectives.

Please leave a comment below for why you think the rate of women who bike to work has stayed flat and decreased, or what you think we can do to change this. Does it have to do with the urban environment, or are the reasons closer to home?

*The same survey also said: Cook County males used the bike for 1.9% of all trips. Cook County females used the bike for 0.8% of all trips.

Table 1 data comes from the 1-year estimates from the American Community survey, table S0801, Commuting Characteristics by Sex for the City of Chicago (permalink), which is a summary table of data in table B08006. Table 2 data directly from American Community Survey table B08006.

How many people ride bikes in Minneapolis and St. Paul compared to Chicago?

I applied for a job on Tuesday in the Minneapolis/St. Paul area (Twin Cities).

I had heard that more people, as a percentage of all commuters, commute by bike in Minneapolis and St. Paul than in Chicago and many other cities. If you’ve been reading Steven can plan for a while, you know that I visited Minneapolis in September 2009 and rented a bike for 24 hours.

I used the American FactFinder to get the details. And now I know what I heard is true.

Chicago Minneapolis St. Paul
Workers over 16 1,230,809 190,814 131,798
Ride bikes to work 12,755 6,770 1,567
Bike mode share 1.04% 3.55% 1.19%

Permalink to data results. Data from the 2006-2008 3-year American Community Survey estimates, table B08301.

Knowing these figures led me to question the nothing that Chicago is a bicycle-friendly city. If it’s so friendly to riding a bicycle, how come there aren’t more people riding their bikes to work?

One of my ideas: There are many trails criss-crossing Hennepin and Ramsey Counties that go to and through major neighborhoods and employment centers. These are essentially bike highways without the threat of a automobiles.

What the Census says about bicycle commuting

UPDATE 11-08-10: I wrote a post comparing the commuting statistics between Chicago, Minneapolis, and St. Paul.

UPDATE 02-12-11: Added 2009 data.

Prompted by this entry on BikePortland about the rise of bicycle commuting and the bicycle mode share in Portland, Oregon, I decided to research what the American Community Survey says about the mode share of bicycles as part of commuting where I live: Chicago. I’ll also post bicycle’s share of commuting for other locales, as well.

Some definitions, first:

  • Commuting means travel to and from work – the Census Bureau calls this “MEANS OF TRANSPORTATION TO WORK.” The Census Bureau does not collect information on travel to shopping, medical services, and other places in the decennial census or the yearly American Community Survey (which will supposedly replace the decennial census).
  • Block means the smallest area for which the Census Bureau reports statistics. Any smaller and the possibility that someone could personally identify you from the responses increases. Find your block. The American Community Survey reports information for much larger areas: In some cases, researchers can only select data at the county level. The Census Bureau provides information for the City of Chicago and other municipal divisions of many counties in Illinois.
  • Subject definitions. These describe the question asked to participants and include clarifying information in the case the participant doesn’t understand the question, or their answer is complex. Download the subject definitions for the 2008 American Community Survey.
  • Margin of error (MOE) means the high and low end of confidence. Read more about margin of error on the Census Bureau’s website.

For the American Community Survey, I found table S0801, Commuting Characteristics by Sex. In the decennial census, I found table  P30. MEANS OF TRANSPORTATION TO WORK FOR WORKERS 16 YEARS AND OVER. If you want to check my research, look for these tables of sample data.

Margin of error for male and female categories varied. Combined always reported 0.2%.

  • 2009 – 1.1% travel to work by bicycle. 1.8% male (MOE: 0.3%), 0.4% female (MOE: 0.1%). Workers over 16: 1,271,744. Permalink.
  • 2008 – 1.0% travel to work by bicycle. 1.5% male (MOE: 0.3%), 0.5% female (MOE: 0.2%). Workers over 16: 1,260,741. Permalink.
  • 2007 – 1.1% travel to work by bicycle. 1.4% male (MOE: 0.3%), 0.7% female (MOE: 0.2%). Workers over 16: 1,230,933. Permalink.
  • 2006 – 0.9% travel to work by bicycle. 1.2% male (MOE: 0.3%), 0.7% female (MOE: 0.2%). Workers over 16: 1,209,122. Permalink.
  • 2005 – 0.7% travel to work by bicycle. 0.9% male (MOE: 0.1%), 0.4% female (MOE: 0.1%). Workers over 16: 1,162,550. Permalink.

United States:
Margin of error happened to be the same for each reported category (combined, male, female).

  • 2009 – 0.6% travel to work by bicycle. 0.8% male, 0.3% female. MOE: 0.1%. Workers over 16: 138,591,804 (decrease). Permalink.
  • 2008 – 0.5% travel to work by bicycle. 0.8% male, 0.3% female. MOE: 0.1%. Workers over 16: 143,995,967. Permalink.
  • 2007 – 0.5% travel to work by bicycle. 0.7% male, 0.2% female. MOE: 0.1%. Workers over 16: 139,259,684. Permalink.
  • 2006 – 0.5% travel to work by bicycle. 0.6% male, 0.2% female. MOE: 0.1%. Workers over 16: 138,265,905. Permalink.
  • 2005 – 0.4% travel to work by bicycle. 0.6% male, 0.2% female. MOE: 0.1%. Workers over 16: 133,091,043. Permalink.

Read the BikePortland article if you want to know that Portland has a higher share of commuters traveling by bicycle than Chicago has.

And what about my block? As I mentioned above, we can only find information at the block group level in the decennial census. I live in Block Group 1 of Census Tract 6009 in Chicago, Illinois. I didn’t live here in 2000, though, the last time the decennial census occurred. Back then, out of 168 workers over 16, 4 of them rode their bikes to work! That equals .024% of the worker population in my block group. Oddly, though, the Census Bureau reported 946 people living in this Block Group. Looking at table P8 (Sex By Age), I see that 674 have at least 16 years of age. 178 people have at least 55 years. Does this mean a lot of people in the Block Group didn’t work at the time of the survey in 2000? I don’t know. Permalink to data.

By far, though, driving alone won as the most popular way to get to work: 71.423% of the worker population.
