Although the Map & Data Library is physically closed, we are still available remotely and happy to help. We can conduct consultations using online teleconferencing software. Please feel free to contact us at mdl@library.utoronto.ca or use our help form. We have a number of tutorials available, are still supplying software licenses, and have compiled a list of resources for working with COVID-19 data.

Please note that our computer lab is also accessible for use through remote access. See this link for more information.

Neighborhood change database (NCDB) 1970-2010

Neighborhood Change Database (NCDB) gives access to US Census data from 1970, 1980, 1990, 2000, and 2010 at the census tract level. The NCDB contains 1970, 1980, 1990, and 2000 Long Form data and the 2010 Summary File 1 and 2010 American Community Survey (ACS) data with details such as: population, household, and housing characteristics, income, poverty status, education level, employment, housing costs, immigration, and other variables. You can access the data for 1970, 1980, 1990, 2000 or 2010 in their census year tract boundaries. In addition, the All years normalized to 2010 selection allows you to compare data for various years. The data for years 1970, 1980, 1990, and 2000 are recalculated and normalized, and the report uses the 2010 tract ID (FIPS code). This allows you to compare data for various years within the exact same boundary definitions.
