It is granted to a formally constituted legal body, such as a court, or to a political leader. It grants authority to deal with and make pronouncements on legal matters and, by implication, to administer justice. Jurisdiction has defined areas of responsibility, e.g. Michigan tax law. Areas of jurisdiction apply to local, state, and federal levels, e.g. the court has jurisdiction to apply federal law. Colloquially it is used to refer to the geographical area to which such authority applies, e.g. the court has jurisdiction over all of Colorado. The legal term refers only to the granted authority, not to a geographical area.
For instance, in large cities such as New York and Los Angeles, a birth doula (one who's hired to assist you with labor and delivery only) can cost $3,500 or more. In other parts of the country, though, you can find a doula for an average price of $500.
The doula determines, for example, how many prenatal and postpartum appointments to have with clients, and at what point in their labor to will join them. Many doulas in the Pioneer Valley area work on a sliding scale basis. Fees in metropolitan areas often run in the range of $2000-$2500 per birth. Midwives who also work as doulas usually earn $1000- $1200+ in Western Mass. Postpartum doulas in the Amherst/Northampton area earn between $15-$35 an hour, with $20 an hour being typical.
