PRESS RELEASE

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.

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.

Statistics Institute's COVID-19 Indicator Platform updated

PRESS RELEASE

Statistics Institute's COVID-19 Indicator Platform updated

April 23, 2020: The Puerto Rico Statistics Institute reported that it has already completed the update of its COVID-19 Indicator Platform in Puerto Rico, after receiving the revised data from the Department of Health. The platform includes graphic representations based on information from single positive cases, using molecular tests, reported since March 9 and purified by that agency, said the executive director of the Institute, Dr. Orville M. Disdier.

The platform has graphs of positive cases, epidemic curve based on molecular tests, daily growth factor based on the date of the molecular test, demographic characteristics and cases by municipality.

“The data provided by the platform will serve as a basis for researchers to carry out their own statistical analysis and generate projections, and that the government can take the actions required to control infections. However, it is important to clarify that the graphs do not reflect all the unique cases, because, as recognized by the Department of Health, there were flaws in the methodology and data collection,” said Disdier.

As he noted, the Department of Health's commitment is to continue sending them daily purified data so that the Institute continues to update the graphics.

“As we have said before this pandemic was declared, at the Institute of Statistics we are in the best position to do everything in our power and in accordance with what the law empowers us, to contribute to transparency in the dissemination of data about this virus,” he said.

The COVID-19 Indicator Platform can be accessed through the following link: Covid-19

Statistics Institute publishes special report for the prevention of school dropout

PRESS RELEASE

INSTITUTE OF STATISTICS PUBLISHES SPECIAL REPORT FOR THE PREVENTION OF SCHOOL DROPOUT

The Puerto Rico Statistics Institute (Institute) today released the special report Early Detection System for School Dropouts for Public High Schools in Puerto Rico: Using Data to Provide Student Support, which provides guidance for the identification and early intervention of students who may be more likely to drop out of school before completing it.

According to the report, although the dropout rate for all grades in Puerto Rico has been decreasing (0.7% in the year 2015-2016 versus 0.9% in the year 2014-2015), the rates by educational level have been consistently higher at the higher level (high school) with 2.3% in the year 2015-2016 versus 0.7% in the intermediate level and 0.1% in the elementary level for that same year. These data justify providing special support to high school students in order to prevent them from dropping out of school.

To access the full report you can visit the following link: 694ec0e7b7a478691ca522cc_IEPR_Perfil_de_Emisiones_Toxicas_2016.pdf

An Early Warning System (EWS) is a series of defined and consistent procedures that, based on student data, allow the teacher to identify early students who are most likely to become school dropouts. “After the student is identified, this system allows the teacher, together with the school management, and subject to available resources, to assign the student one or more interventions with the purpose of reducing the likelihood of dropping out of school, without stigmatizing the student,” explained Dr. Orville M. Disdier, senior manager of Statistical Projects at the Institute and author of the report.

The characteristics or variables that were most important when predicting the probability of dropping out of school were: the results of standardized science tests, grades in English, grades in Spanish and unexcused absences. For example, as soon as a student scores a C in English or Spanish subjects, or accumulates 2 to 4 unexcused absences, they could be classified as having a “moderate risk of desertion”.

On the other hand, as soon as a student scores D or F in English or Spanish subjects, or accumulates a total of 5 or more unexcused absences, they could be classified as having a “high risk of desertion”. Depending on each case, the student may be assigned general or individual interventions. For example, general interventions could include sending written, telephone or electronic communications to parents/guardians and group workshops, and others. On the other hand, individual interventions could include personalized meetings and the assignment of a student mentor, among others.

With the Early Detection System or EWS, for its acronym in English, for School Dropouts, the Institute seeks to empower our teachers and principals with the best that science has to offer, in terms of early detection of students at high risk. As with almost any social problem, prevention is the key and for that we need tools to help us identify those students at risk in a timely manner.

“In order to be fully effective, of course, identification without intervention is totally ineffective. The intervention is up to teachers, principals and more broadly to the Department of Education, subject to the resources available to carry out some of these interventions. The purpose of this report is not to announce the interventions, but rather to identify students using scientific data in a way that is easy to implement in the classroom, and at the same time to appreciate how this knowledge can be used, we present some interventions that have been used in other places successfully and that in some instances already exist in Puerto Rico,” said Dr. Disdier.

For his part, Dr. Mario Marazzi-Santiago, executive director of the Institute, pointed out that Act No. 165-2011 of July 29, 2011 amended Article 1.03 of Law No. 149 of July 15, 1999 (Organic Law of the Puerto Rico Department of Education) in order for the Institute to develop, together with the Department, an EWS for school dropouts. “With the publication of this report, we are complying with our responsibility to the law, and establishing the theoretical and practical bases for the possible establishment, for the first time in Puerto Rico, of an EWS, which would unite us with the more than 31 states and territories of the United States that have this type of system,” said Dr. Marazzi-Santiago.

The Puerto Rico Statistics Institute is an autonomous governmental entity responsible for coordinating the Government's statistical production service to ensure that the data collection and statistics systems, on which public policies are based, are complete, reliable, and have quick and universal access. The IEPR has in its inventory, accessible through www.estadisticas.pr.gov, about 300 statistical products. In addition, it is a custodian and provides access to over 100 data sets or “data sets” through www.data.pr.gov And to over 40 tables and more than 6 thousand indicators through: www.indicadores.pr

In addition, as the leading entity of Puerto Rico's SDC, the IEPR 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 and official statistics on Puerto Rico's decennial population and housing censuses, among others.
