RED STATE DATA CENTER OF PUERTO RICO (SDC‐PR)

Population under 18 has fallen by 36% over the decade

According to new estimates of the population by age and sex 2010-2019

San Juan, PR, June 25, 2020 — The U.S. Census Bureau today released the most recent Annual Population Estimates by age and sex characteristics for municipalities, Puerto Rico and counties in the United States. These statistics refer to July 1, 2019 and include population estimates by age group for each municipality.

On behalf of the State Data Center Network of the U.S. Census Bureau in Puerto Rico, the Puerto Rico Statistics Institute (Institute) reported several findings from the new publication of population estimates for 2019 compared to those of July 1, 2010:

  1. From 2010 to 2019, the population under 18 years of age in Puerto Rico reflected a reduction of 324,293 residents, representing a percentage change of ‐ 36%. As of July 1, 2010, this population was 897,024, nine years later in 2019 it is estimated at 572,731.
  2. In terms of the proportion of large age groups in the population, those under 18 used to represent 24% (2010) in Puerto Rico, now they comprise 18% (2019).
  3. The population structure by age and sex (pyramid) of 2010 compared to that of 2019 shows how the composition has changed rapidly in Puerto Rico. Its base is much narrower, indicating a decline in infants, children and adolescents.
  4. On the other hand, the top of the pyramid reflects a significant increase in age groups aged 65 and over, which translates into an older population.
  5. Puerto Rico's median age is estimated to have increased about six years over the decade, from 37.0 years in 2010 to 43.2 years in 2019.

“The estimates by demographic characteristics of age and sex allow us to detail the population trend in Puerto Rico. For example, the drastic decline in births has a direct influence and is reflected at the base of the population pyramid. As of 2010, the population in age groups between 0-4 and 5-9 years comprised about 3% of women and men, respectively. In 2019, the base shrank with percentages close to or below 2%,” said Alberto L. Velázquez-Estrada, Manager of Statistical Projects at the Institute.

The 2019 annual population estimates for Puerto Rico and its municipalities can be accessed on the census data and information page on Puerto Rico of the SDC‐PR network at: https://censo.estadisticas.pr/EstimadosPoblacionales, and more details on the annual estimates at: census.gov/programs‐surveys/popest.html.

The Institute is an autonomous governmental entity tasked with coordinating the Government's statistical production service to ensure that the systems for collecting data and statistics, on which public policies are based, are complete, reliable and accessible quickly and universally. In addition, as the leading entity of the SDC in Puerto Rico, the Institute manages the SDC portal, which contains the main statistical reports and publications of the U.S. Census Bureau on Puerto Rico, specifically those that are most in demand, such as annual population estimates; the Puerto Rico Community Survey (Puerto Rico Community Survey) and official statistics on Puerto Rico's 10-year population and housing censuses, among others. The Puerto Rico SDC portal can be accessed at: https://censo.estadisticas.pr/.

Statistics Institute and Instituto Nueva Escuela manage to include Montessori schools and questions about the impact of Hurricane Maria in an important school survey

PRESS RELEASE

Statistics Institute and Instituto Nueva Escuela manage to include Montessori schools and questions about the impact of Hurricane Maria in an important school survey

The 2019 edition of the YRBSS for Puerto Rico included students from Montessori schools for the first time and asked about the effects of the hurricane on these students

The Puerto Rico Statistics Institute joined forces with the Instituto Nueva Escuela, achieving for the first time that Montessori schools are included in the 2019 edition of the survey Youth Risk Behavior Surveillance System (YBSS). The YRBSS is a survey conducted every two years to students in grades 9, 10, 11 and 12 across the United States and its jurisdictions, including Puerto Rico. The questions cover various topics related to students' health and risk behaviors, and as a result, statistics are produced on bullying, electronic harassment, violent behavior, sexual behavior, drug use and on students' eating habits, among others.

In addition, it was possible to include five additional questions, related to the impact of Hurricane Maria on students, from all the schools participating in the study in Puerto Rico. Approximately 1,498 students from public schools in Puerto Rico participated in the self-administered survey, and of these, a total of 110 students belonged to Montessori schools, of which 53% were male, 47% female, and 27.2%, 54.5%, 16.0% and 2.3% were in grades 9, 10, 11 and 12, respectively. Although it is expected that by the end of this year the Institute of Statistics and the Instituto Nueva Escuela will produce an official and detailed statistical report on the results of this survey, here are some preliminary results regarding hurricane questions in students under the Montessori philosophy:

  • 80.4% of students reported that they spent a month or more without electricity in their homes.
  • 98.9% of students reported feeling sad or hopeless after the impact of Hurricane Maria and due to the lack of electricity.
  • 47.1% of students reported that they spent a month or more without drinking water service in their homes.
  • 100% of the students reported feeling sad or hopeless after the impact of Hurricane Maria and due to the lack of drinking water.
  • 77.7% of students reported that they were unable to attend school for a month or more because it was closed or unable to reach or access it.

“These preliminary results show us the enormous impact that the passage of Hurricane Maria had on these Montessori school students. In previous editions, these students, under the Montessori philosophy, were left out of this important survey. However, thanks to the teamwork of both institutes, we have been able to make them visible,” said Dr. Orville M. Disdier, executive director of the Institute of Statistics.

For their part, Dr. Ana María García Blanco, executive director of the Instituto Nueva Escuela, and Mr. Cesar Ostolaza of the Evaluation and Research Division said: “We are very happy with the invitation from Dr. Orville M. Disdier to participate in this study. It is important to have reliable data in the face when making decisions about the practices and services we will provide to our students. Their voices are essential in defining the public policies for which we are choosing. It is imperative to take into account the emotional state of young people, especially based on the natural and social phenomena they have been through when it comes to “building” a school. It is with them and from them that we must build it.”

The Instituto Nueva Escuela is a non-profit entity that seeks to transform the public education system in Puerto Rico through Montessori philosophy and methodology. For its part, the Statistics Institute of Puerto Rico is a governmental entity with fiscal and administrative autonomy with the mission of coordinating the statistical production service of government entities.
