These GIS SHP files cover the spread of different modes of transportation in the Lower 48 states from this nation’s founding through (approximately) 1911.  Each transportation mode–canals, steamboat-navigated (as opposed to navigable) rivers, and railroads–has its own archive ZIP file which contains the complete series of files (projection, database and polyline files, etc.) required by ESRI’s ArcGIS and ArcGIS Pro.  These are collectively referred to as “a SHP file” though there are actually multiple files for each mode of transportation.  Once unpacked, these files for each SHP must be kept together and should only be edited using a GIS program.  If corrupted, the entire SHP file will become unusable.

The metadata file (.XML) briefly describes the contents of each SHP, the manner in which it was created, and summarizes any edits since these files were originally posted.  Issues relating to the creation of these SHP files are discussed in much greater detail in the documentation below.  That documentation covers the three modes of transportation for which I have created SHP files.

Please contact me if you have any corrections to these SHP files.

I also draw attention to my June 2013 article in the Journal of Economic History that describes an earlier generation of SHP files which these files replace. A link to this article appears on my home page (see the navigation bar above).


Procedures and Issues Relating to the Creation of Historical Transportation Shapefiles of Navigable Rivers, Canals and Railroads in the United States

These data were collected under the sponsorship of the National Science Foundation through a variety of grants to Fred Bateman, Thomas Weiss, and Jeremy Atack. We gratefully acknowledge their generous support.

The data here are provided here in the form of Microsoft Excel 2010 files.  These same basic data are also available from ICPSR at the University of Michigan which is the “official” designated depository.

Be sure to also download the related documentation.

State level samples (representative of the individual states but NOT nationally representative)

National samples (representative of the country as a whole and individual regions)



I am currently working on a nominal record linkage program that will ultimately create an unbalanced panel of individual and family/household census records from the federal censuses of population in 140 townships from coast to coast in the northern part of the United States linked to the farm records from the federal agricultural censuses from 1850 through 1880.  Thus persons in the 1850 population census are linked to the 1850 cenus of agriculture if they operated a farm within the sample township.These linked records are, in turn, linked to the 1860 census of population for the same township with these data also linked to the 1860 census of agriculture, and so on.  No effort is made to trace out-migrants or in-migrants in the sample townships although this is certainly possible (for men, anyway) using the census indexes created by

Since persons are linked using their name (supplemented by other characteristics such as age, occupation, birthplace, the names of other family members, etc.), women who (re)marry are generally “lost.”

As panels become available, they will be linked here.

This project also led to the creation on a public domain nominal record linkage program, PCMatchmaker, which may be downloaded here,  The program is stored as an archive and contain 104 files.  These should be extracted and kept together in a single directory.  Potential users should consult the documentation below before running this program.

Although this program was written prior to Windows (especially the current 64-bit version) it still runs (as of November 2016) in a command line window (“PCM.BAT”–see the documentation below), found under “Accessories” in the Windows Start Menu.

The documentation for the PCMatchmaker program is here and an academic paper which describes this program may be downloaded here.
