Introduction Natural resource use and access have long been thought to be important in shaping rural fertility patterns Many hypotheses have been proposed to explain the relationships between natural resources and fertility This study tests these natural resource-fertility hypotheses in the Petn, an agricultural frontier in Northern Guatemala

high rates of deforestation Deforestation in the Petn Data and Methods Data for this study comes from the 1998/1999 Encuesta de Salud Materno Infantil Individual questionnaires
Data and Methods In addition, in the Petn, a household survey on health, migration, and natural resources was conducted Data and Methods Multivariate regression (n=404) Do natural resource variables predict the number of living children?
Controls in the Model Maternal factors Household factors Hypothesis Supported? Land Labor Hypothesis Land Security
