## Description
-In this challenge you must analyze demographic data using Pandas. You are given a dataset of demographic data that was extracted from the 1994 Census database.
-
-You can access the full project description and starter code on repl.it.
-
-After going to that link, fork the project. Once you complete the project based on the instructions in 'README.md', submit your project link below.
-
-We are still developing the interactive instructional part of the data analysis with Python curriculum. For now, you will have to use other resources to learn how to pass this challenge.
