Guide Description

This guide provides mainly census data that may be used by students to calculate the percent of increase or decrease in population at the state, county, and town levels. The data is taken from atlases, plat books, and maps. Most of the data is from 1790-1915. Additionally, there are charts on juvenile delinquency in Hennepin County from 1914-15. All of the data could be used to create pie graphs or histograms. In the process, students would be analyzing the population growth, along with several social issues, during this time period.

Things to Think About

How did the population in the United States increase from 1790 to 1870 and specifically in a particular state? What is the ethnic background of Minnesotans? How did the population in various towns in Minnesota change from 1914 to 1967? What is the increase in juvenile delinquency from 1905-1915? How do statistics help us to better understand social issues?

Keywords

Census, population, health records, temperance

Other ideas (to assist with discovery)

The Juvenile Court of Hennepin County 1914-15 gives a wealth of information on juvenile delinquency. I have included two pages to give a sample, but there are many charts of the type of crimes, explanations of why the numbers are changing, and descriptions of the where the children are sent for rehabilitation. The county plat books give interesting additional information on world events, such as the decrease in distances by going through the Panama Canal, and charts on population, area, commerce, and debt for countries around the world.

Challenges to finding resources on this standard

There are many items for the keywords; the challenge is in finding items that contained charts or graphs with statistics. There are resources dealing with social issues; however, many do not include statistics or some of the information may be above the comprehension level of seventh graders.

10: Helpful Tips (optional)

In the Atlas from 1870, the population charts go back to the census of 1790. Some states do not have data going back to that date; data for each state begins with the census after statehood. There are many official maps of Minnesota; I selected the 1967 map because this gave the population data for towns from the 1960 census and this could be compared to the fifty year change in population from the 1910 census data that is available in the 1914 Atlas and Farmers' Directory of Mille Lacs Co. The more current maps could be used to compare census data in the last half of the 20th century. All of the information in the Juvenile Court of Hennepin County should be very interesting to seventh graders. The descriptions are easy to read and could be used as an integrated unit in reading and social studies. Each of these books contains multiple pages which provide a variety of statistics.

11: Ideas for Lesson Plans Using this Guide (optional)

The first page cited from the Atlas and Farmers' Directory of Mille Lacs Co, contains a great map of the Panama Canal and provides a bar graph of distances that were saved between various cities by going through the canal. This could be used to introduce students to the concept of using real world situations to create graphs. They could also use this information to calculate the percent of decrease in mileage. From the 1870 Atlas, students could select various states and make graphs of the change in population and then calculate the percent of change. This could also be done with the statistics on the various towns in Minnesota in the Mille Lacs Co. Directory and the 1967 highway map. Students could create a pie graph of the ethnic background of Minnesotans found in the 1870 Atlas. The world map data found in the Crow Wing Co. plat book could be compared to current population data. Several of the charts in the Juvenile Court record compare crimes, new cases, and expenditures at the Glen Lake Farm School for Boys from 1914 to 1915; so again, students could graph this information and calculate the percent of increase or decrease. For further understanding, the chart from the state board of health could be used to create a histogram comparing heights of boys and girls from 1879 with heights of boys and girls today. Statistics dealing with the social issues at the turn of century could be compared and contrasted with similar issues today.
