Cemetery Demography - Survivorship and Population Structure - (ESA EcoEd Digital Library)

This module allows for comparisons of survivorship data among and within cemeteries. The databases contains data from seven cemeteries in the Wyoming Valley of northeastern Pennsylvania, collected by students in Wilkes University's BIO 344 Ecology course. Data from other cemeteries can be uploaded, by each individuals, for further analysis. Instructions for uploading additional data are provided below.

Uploading Data

The Survivorship Data component outputs data from one of the selected cemeteries, or from a user uploaded dataset (MyData1-5). You may learn more about uploading and using your own data here. Uploaded data must be no larger than 200KB, and conform to the Demography Data Format. The file format must be in a .txt or .csv.

Demography Data Format

The Demography Data Format is 5 columns of comma separated values, with these exact column names:

Name,Sex,Birth Year,Death Year,Age(years)

In each data row, Name should be specific to the individual, either a name abbreviation or unique number, sex should be specified with one character, and birth year and death year in YYYY format. E.g.:

Ada J,M,1867,1910,43
All S,F,1838,1932,94

Science Pipes Operations for Survivorship Data

Data may be filtered by individuals' year of birth, year of death, age at death, and sex.

The Data Grouper actor is used to group ("bin") data by a selected Group By parameter, into bins of a specified size. For example, a user can bin data by age at death, into intervals of 5 years, and then feed this grouped ("binned") data into the Histogram component to see frequency of death by age intervals.

The Survivorship Calculator component outputs a summary Life Table, which may be viewed with the Data Viewer component. It also outputs each individual column of the life table, and these may be used to produce line charts (e.g. survivorship curves) using the Line Chart actors.

My dual credit biology class has been collecting a large amount of data from the cemetaries in our county. However we haven't been collecting the names just age, sex, birthdate, and deathdate in an excel spreadsheet. I think this would be a good tool to use in their analysis but I am not sure how to transfer and enter the data. Any suggestions?

Hi Danielle. You'll need to add a Name column (and have your data in the exact format required: ).
I don't recall restricting the Name column to letters only, so an easy workaround would probably be to use Excel to generate the Name column with increasing numbers as stand-in for names. E.g.:

Name,Sex,Birth Year,Death Year,Age(years)

Export your data to csv, and then upload it:

Hope this helps.
