Tsimane' Amazonian Panel Study: Publically Available Data on Indigenous People

TAPS evaluates the effect of market exposure on a wide range of indicators of well-being and the environment by drawing on theories from economics, evolutionary biology, and cultural anthropology. The signature of the multi-disciplinary project is the collection of panel or longitudinal data— repeated observations over time from the same people, households, and villages— to permit a dynamic, comprehensive view of how larger processes taking place at regional and global scales affect the well-being of villagers and their environment. We follow about 1,800Tsimane’ in all 260 households of 13 villages along the river Maniqui, Department of Beni. Villages differed in their closeness to San Borja (mean=25.90 Km; SD=16.70). Differences in village proximity to San Borja and the longitudinal dimension of the study allow one to capture both temporal and spatial variability in market exposure.

(a) Introduction to the panel

TAPS has just released the 2002 - 2006 (inclusive) panel data (for the history of TAPS see Tsimane’ Amazonian Panel Study: The first five years (2002-2006) of data available to the public in 2008). The study of those changes through panel observations can yield very valuable information about how processes such as globalization, market exposure, or trade opening affect cultural (identity, local ecological knowledge), economic (income, consumption), psychological (happiness), and biological (health, nutrition, growth) dimensions of well-being. The panel data set we are making available was preceded by seven years (1995-2001) of pilot research that served to identify communities, win the trust of villagers, train local researchers, build logistical infrastructure, and refine methods of data collection. This panel data set only includes variables that were measured annually during 2002-2006.

The 2002-2006 data is in STATA 10 and is available by contacting R. Godoy (see section (b) below). To use the data, users should draw on two documents: (a) TAPS Data Dictionary only variables in ALL years an Excel spread sheet that lists all the variables and any variation between years in the definition of the variable and (b) TAPS Data Dictionary only variables in ALL years a text document that lists all the variables in alphabetical order and describes them

(b) Requesting the data and Confidentiality agreement

The TAPS Panel Data set is free and open to the public. However, confidentiality of our respondents is very important. We have taken care to ensure that our data cannot be used to identify individuals, households, or communities.

To further ensure confidentiality, if you would like to use our data, we ask you to send a letter (SID, Heller School for Social Policy and Management, Brandeis University, Waltham, MA 02454, USA) or an email to rgodoy@brandeis.edu. The email requesting the data should read as follow:

"Your complete name:

Dear Mr Godoy:

I am interested in using the 2002-2006 TAPS panel data set. In requesting the data I agree to the following:

  • Use the TAPS panel data set for research or educational purposes only
  • Not attempt to identify any individual, household, or community
  • Not share the copy of the data with other users who have not agreed to these confidentiality terms.
  • Any publication resulting from your request must: (a) include you as an author or as a co-author and (b) acknowledge the Program of Cultural and Biological Anthropology of the National Science Foundation (NSF) in the USA and TAPS for making the data available.

Sincerely yours,

Your name"

After Ricardo Godoy receives the email agreeing to these conditions and providing this information, you will receive the zipped 2002-2006 TAPS data in STATA 10.

(d) Supplementary information

Besides the variables measured every year during 2002-2006, TAPS also collected variables in only some years. These are not included in the 2002-2006 data set, but can be reviewed in the following document: TAPS Data Dictionary ALL variables (excel) If you would like access to some of the variables that appear only in some years, you should note this when they request the data.

(e) We would like to hear from you

We would like to hear from you if you encounter problems using the data, or if you have trouble understanding the meaning or construction of variables. If you have questions about the TAPS data set, contact:
